With the entry of artificial intelligence and information technology, people's life has become more and more intelligent and information-based. Family life is essential for most people. In people's past subjective consciousness, housing only needs to meet people's living needs. Now people are more pursuing comfort, efficiency, safety, automation and intelligent high-level enjoyment, thus intelligent furniture came into being. Wireless communication is a communication method that uses electromagnetic wave signals to exchange information in free space. Compared with traditional communication methods, this communication method is more convenient and intelligent. While Internet technology has been widely used, wireless communication technology has also been continuously promoted and developed. A variety of mature network protocols have provided technical support for intelligent furniture and finally, realized a smart living environment. At present, the intellectualization of furniture design is mainly focused on the furniture itself, so it can only meet part of the needs of users and cannot realize the remote control of furniture equipment by users. This has affected the user's demand for furniture products in the next step and also affected the user's pursuit of a higher quality life. Under the background of intelligent furniture, this paper studied the mobile intelligent terminal in furniture design with wireless communication technology and proposed a mobile intelligent terminal system based on Zigbee wireless network communication technology by analyzing the functional partition and functional module design of intelligent furniture. Then, in order to make the network allocation in the system more reasonable, a distributed intelligent scheduling model of anti-interference link resources in wireless communication network was built. The final experimental results showed that the mobile intelligent terminal system proposed in this paper realized the remote control of intelligent furniture and a higher level of living environment and improved the satisfaction of furniture products by 4.21%. This also provided valuable reference for the next application of wireless communication technology in the home field. [ABSTRACT FROM AUTHOR]

Recently, due to the fast development in multimedia applications of wireless communication systems and demands of increasing the capacity and data rates to meet the requirements of 5G mobile communication systems, new transmission techniques are needed. One of the powerful enabling tools of the 5G communication systems is the multi-input multi-output (MIMO) antenna system employing multiple antennas and utilizing the multipath fading mobile environment to increase the channel capacity without any additional bandwidth and/or transmitted power. However, because of the limited space of mobile devices, the distances between antennas are decreasing. The mutual coupling between antennas severely affects the overall performance of the MIMO system. So, isolation improvement methods are applied to reduce these influences. In this review, different isolation techniques and their features and drawbacks are presented, and the techniques for applying them in modern MIMO antenna systems are illustrated. Besides, the performance characteristics of these MIMO systems are compared. The review also contains basic concepts of the MIMO antenna system and its performance metrics. Finally, the future directions and trends for the MIMO antenna system design are discussed briefly. [ABSTRACT FROM AUTHOR]

The Internet deconstructs and reshapes the traditional classroom organization, the status of teachers, the authority of teaching materials and the role of students. Online Ideological and political education with the help of the Internet has become an inevitable trend of Ideological and political education. Mobile edge computing solves the high delay barrier when traditional cloud computing center provides services. It is a new technology with wide application prospects, which provides convenience for online education. At the network edge, the mobile edge computing service network can be established due to the deployment of small base stations. Mobile users can upload and migrate some computing intensive or delay sensitive tasks to the currently connected small base station, and then the mobile edge computing network uses the hardware resources on the small base station to assist users in processing such tasks. Face verification technology can be widely used in access control, attendance, government convenience services and other occasions that need identity verification. Hence, this paper proposes the immersive online biometric authentication algorithm for online guiding based on face recognition and cloud-based mobile edge computing. We use the combined technologies to construct the efficient model. The proposed framework is validated compared with the other state-of-the-art methods. [ABSTRACT FROM AUTHOR]

With the continuous advancement of science and technology, the improvement of mobile terminal hardware performance and the large-scale popularization of smart phones have brought new experiences and methods to surveying and mapping work. This article mainly studies the application of remote sensing image processing technology based on mobile augmented reality technology in surveying and mapping engineering. First, perform grayscale processing on the image in the experiment, then remove the noise in the image and smooth the image through the median filter method and finally use the Canny operator to perform edge detection to obtain a binarized image containing only the target object, and this is done by image feature extraction. After using three-dimensional scanning modeling to extract the image feature points, the target manager is used for sample analysis. Obtain the projection matrix through the interface, and then perform coordinate conversion to complete the positioning of the target scene. In this paper, the BRISK feature point detection algorithm with fast speed and small calculation is used to detect the target, and SVM is used for remote sensing feature classification. Experimental data show that the recognition success rate of the algorithm is 84%. The results show that mobile augmented reality technology and remote sensing image processing technology can improve the efficiency and accuracy of surveying and mapping engineering, and have strong ease of use and stability.

In view of the obvious deviation of traditional methods in the analysis of basketball flight state, a basketball trajectory analysis method based on intelligent image of mobile terminal is designed. Firstly, the mobile terminal network equipment is used to effectively collect the basketball trajectory. The gray pixel set of basketball image is obtained. Combined with the nonlinear transformation method, the color of basketball image is enhanced and the image quality is effectively improved. Based on this, the running process of basketball is analyzed from two aspects of initial angle and initial running speed. High quality basketball trajectory image can ensure the accuracy of initial angle and initial running speed analysis. The experimental results show that the MAE value of this method is always lower than 0.1, the F-measure value is relatively high, and the duration of trajectory analysis is between 0.72 s and 0.81 s, which fully proves the effectiveness and feasibility of this method.

Next generation multimode terminals have the capability to support different classes of calls simultaneously as well as the ability to connect to two or more radio access technologies (RATs), at the same time, in a heterogeneous wireless network. For a mobile terminal having multiple classes of simultaneous handoff calls (such as file download and video sessions), RAT selection decisions can be made independently for individual calls in the group or jointly for the entire group of calls. Both independent and group RAT selection decisions for multiple calls have advantages and disadvantages. Existing RAT selection algorithms have focused on RAT selection decisions for single calls. Therefore, this paper investigates independent call and group call RAT selection decisions for multiple calls in heterogeneous wireless networks, and proposes a scheme that makes RAT selection decisions for multiple calls based on a consensus level among the multiple calls to be admitted. When this consensus level is among multiple calls to be admitted into a particular RAT and is equal to or above a certain threshold value, a group decision is used. Otherwise, independent decisions are made. The performance of the proposed RAT selection scheme is evaluated in a three service three RAT heterogeneous network, supporting multihomed terminals. Simulation results are given to show the effectiveness of the proposed scheme. [ABSTRACT FROM AUTHOR]

Miner’s wearable robot is an important mobile terminal of the monitoring network for the coal mine production safety. However, it is difficult to find the study on the miner’s emotion change using brain-computer interface (BCI) for miner’s wearable robot, especially for the smart helmet. This paper explores the anxiety change rule and the detection method using BCI of miner’s smart helmet. There are three contributions in this paper. Firstly, an emotional state evoked paradigm is designed to find the brain area where the emotion feature is most obvious. Then, the accurate electrode position is determined for the electroencephalograph (EEG) collection of the negative emotion on the basis of the international 10-20 systems. Secondly, a fusion algorithm of the anxiety level is proposed to evaluate the miner’s mental state by using the θ, α, and β rhythms of EEG. Thirdly, the miner’s smart helmet system is built to collect the human state which includes the mental parameters of the anxiety level, the fatigue level, the concentration level, and the environmental parameter in coal mine. Experiments demonstrate that the position Fp2 is the best electrode position for obtaining the anxiety level parameter. The most obvious EEG changes appear within the first 2 s after the stimulator works. The amplitudes of the θ rhythm increase most obviously in the negative emotion. In addition, the fusion algorithm of the anxiety level parameter has a good following function to the negative emotion change. This method can reflect quantitatively the anxiety level of a human. So it is avoided for the miner to operate improperly, and then the operation safety can be improved. [ABSTRACT FROM AUTHOR]

Fine art sculpture refers to decorative objects and commemorative objects shaped to beautify the environment or memorial meaning, and have a certain meaning, symbol or shape. Reversible image steganography cannot only protect the invisibility of the image, but also completely restore the original carrier. There are various forms of reversible information carriers, such as images, text, audio, and video. Among them, JPEG images are often used as transfer objects in life, so the research of image steganography algorithms based on JPEG images has received widespread attention. This paper analyzes the various features of existing reversible information splicing algorithms for JPEG images theoretically, and compares various advantages and disadvantages through experimental research, and summarizes the system design of JPEG image reversible information splicing technology. At present, it mainly includes: can improve dense images proportional distortion performance; dense images at the file extension level can be controlled more economically; algorithm design should measure both the proportional distortion performance and the file extension at the same time. This paper also proposes a reversible information splicing algorithm for JPEG images based on multi-objective optimization. When designing the algorithm, the rate-distortion performance and file extension of confidential images are considered. A mathematical model for multi-objective optimization is proposed and designed for two goals the corresponding function is used to better measure the performance of the confidential image.

One of the key issues in cellular mobile communication is to find the current location of mobile terminal (MT) to deliver the services, which is called location management (LM). Much research has been done on dynamic LM that reduced the LM cost up to a large extent. In movement based dynamic LM scheme, the location area is defined in the form of ring of cells for individual user. Whenever an MT visits a cell outside of its current location area (LA), it triggers location update (LU). For this purpose, network must inform the mobile terminal about ID of all the cells present in its current location area. In this paper, a simple way of cell-ID assignment is proposed under which, network sends only the ID of center cell of LA ring to MT and then MT can compute IDs of all other cells in its location area. This saves a significant amount of wireless bandwidth by minimizing the signaling traffic at VLR level and thus reduces the mobility management overhead. [ABSTRACT FROM AUTHOR]

Next-generation mobile communication systems require high data transmission rate and low bit error rate, but multi-path fading still stands as a major problem. Antenna diversity techniques can overcome the problem. In this paper, we thoroughly study the antenna diversity performance on a mobile terminal through theoretical analysis, computer simulations, and practical prototype measurements. Specifically, a genetic methodology is developed to accurately evaluate the diversity gain achieved in the mobile terminal from both power level approach and correlation approach. Throughout the simulations and measurements, we demonstrate that it is beneficial to implement antenna diversity on mobile terminal side, and high diversity gain can be achieved when the antennas are placed in the terminals properly. Moreover, further improvement of the diversity gain can be obtained from the implementation of the matching networks. [ABSTRACT FROM AUTHOR]

Mobile communications and wireless networks are developing at a fast pace. The increasing number of mobile subscribers and terminals are the real life evidence of the fast growing development in the area of wireless communication. Wireless communication technology is now pursuing 4G (fourth generation) and seeking a scheme to provide quality of service (QoS) to the various applications continuously even moving to another network. In this paper, we proposed a dynamic resource management architecture which considers vertical handoff situation with minimal disruption of service to the users considering seamless provision of QoS. The proposed scheme efficiently manages resources and provides stable services to the mobile terminal. The simulation results show that resource management enabled mobile terminals utilize system resources, CPU and memory, efficiently improved by 40% and 65%, respectively, rather than mobile terminals without resource tuning.
