Abstract

The rapid evolution of the International Mobile Telecommunications (IMT) landscape has prompted the International Telecommunications Union Working Party 5D (ITU WP5D) to outline the framework for IMT-2030 and beyond. This next-generation initiative seeks to meet the diverse demands of future networks, with key objectives including hyper-low latency, enhanced energy efficiency, and robust support for high mobility. Current 5th generation (5G) technologies employ waveforms like Orthogonal Frequency Division Multiplexing (OFDM) and Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM). However, these waveforms are insufficient to fully meet the stringent requirements of next-generation communication systems. This paper introduces a novel waveform, Orthogonal Time Frequency Division Multiplexing (OTFDM), designed to address the limitations of existing waveforms. OTFDM achieves ultra-low latency by enabling single-shot transmission of data and Reference Signals (RS) within a single symbol. Furthermore, OTFDM supports high mobility with improved resilience to Doppler shifts and enhances power amplifier efficiency through its low Peak-to-Average Power Ratio (PAPR) characteristics. The proposed waveform incorporates advanced signal processing techniques, including time-frequency multiplexing and frequency domain spectrum shaping, to mitigate inter-symbol interference (ISI). These techniques enable accurate per-symbol channel estimation, thus supporting higher-order modulations even at higher user speeds. Extensive simulations validate the efficacy of OTFDM, demonstrating its capability to support user speeds up to 500 Km/h with minimal RS overhead. This paper explores the technical aspects of OTFDM and discusses its potential implications for the next-generation wireless communication systems.

36. Cultural constraints on knowledge transmission and knowledge erosion: An indigenous community in India

Author

Koteswara Rao, Kodirekkala

Abstract

The paper aims to add a novel dimension to the ongoing discourses on the erosion of indigenous knowledge. The loss of indigenous knowledge as a result of external forces (of modernization, market economy, development, and globalization) has been well documented. There is, however, a lack of understanding about the internal constraints or cultural factors, which may be as important as external (outside) factors in the erosion of knowledge. Extending the focus to internal cultural factors for effective knowledge management is also imperative. Therefore, the present study will examine this issue from a different perspective and with specific reference to the ethnomedicinal knowledge among a tribal society (the Konda Reddis) in South India. The paper discusses how internal constraints– such as social restraints of supernatural forces, and disruptions in knowledge transmission – are playing a critical part in the erosion of indigenous medicinal knowledge.
