Research on Error Analysis of Data throughput and BER for the Wireless OFDM PSK Network

Abstract

Wireless Communication is one of the greatest contributions to mankind. The main goal of wireless communication is to provide communication with high data rates. During this transmission over a wireless link, the sidebands from various carriers might overlap and give rise to interference. OFDM combats these interferences. OFDM is a multicarrier technique in which high data single stream are transmitted over a number of minimum data rate parallel sub-carriers. Due to this, the symbol duration tends to increase and reduce the effects of multipath spread delay. Also, for spectral efficiency, the cognitive radio is designed to utilize the best channels in periphery. It automatically detects the ready to be drawn channels in a wireless spectrum and then transmutes the reception and transmission parameters accordingly. In this paper, the error analysis is presented in OFDM system error correction with PSK modulation by using forward codes (Reed-Solomon codes and Bose–Chaudhuri–Hocquenghem codes) in order to get low BER, high data rate and also resilience the interferences in AWGN, RICIAN, RAYLEIGH channels and the result is stimulated using LABVIEW. Wireless communication has become vital which uses free space as a communication channel, the cognitive radio is a technology which proved that it is best in the developing wireless systems.
