Free space optics (FSO) systems have gained considerable attention because of their numerous features and services. It has evolved into a promising technology for high data rate transmission in wireless communication systems. However, there are some atmospheric effects which inhibit its performance. In this paper, performance of code division multiple access–free space optics (CDMA–FSO) by combining multidiagonal (MD) codes and orthogonal frequency division multiplexing–free space optics (OFDM-FSO) systems over using advance line coding formats under the sway of turbulence conditions are investigated and compared. A comparative study has shown that CDMA–FSO offers better SNR with both CSRZ and AMI coding format under diverse conditions at data rate 15 and 20 Gbps. [ABSTRACT FROM AUTHOR]

The importance of research in education is universally accepted. Driving the past two decades, there have been numerous studies, policy documents highlighting the 'importance of research" which India could reap by improving the research infrastructure in Higher education. The present paper traces the regulatory policy and structure of higher education in India since post-Independence(after 1947) period. A detailed analysis is carried out about the the government emphasis on research front. A critical analysis is carried out of the policy initiatives during these years including the New Policy on Education(1986), AICTE and UGC notification in 2010, the Yashpal Committee Report; the National Board of Accreditation(NBA);the National Assessment and Accreditation Council(NAAC); which has resulted on increased emphasis on faculty research. The paper finally assesses the impact of these efforts and development from the perspective of quantity and quality of research publications. [ABSTRACT FROM AUTHOR]
