BER Performance of OFDM Technique using RS Coding for Wireless Communication Systems

Abstract

Orthogonal frequency division multiplexing (OFDM) is becoming the most important modulation technique for wireless communications. High capacity and variable bit rate information transmission with high bandwidth efficiency are just some of the requirements that the modern transceivers have to meet in order for a variety of new high quality services to be delivered to the customers. Digital modulation techniques contribute to the evolution of our mobile wireless communications by increasing the capacity, speed and quality of wireless networks. But the BER is the major part of any modulation technique. In this paper, the BER performance of various modulation techniques like BPSK, QPSK,
