Reed Solomon Coding in Orthogonal Frequency Division Multiplexing (OFDM) Communication Systems


This paper presents a MATLAB simulation that has been developed to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication system using Reed Solomon (RS) Coding process. The efficient encoding and decoding algorithm, and the powerful of error correction capability of Reed Solomon Coding make it one of the most widely used error correction codes algorithm, so we use it with OFDM systems to merge the benefits of multicarrier modulation and Reed Solomon Coding to obtain system that has excellent performance capability in multipath and fading channels. Single-carrier QAM and multicarrier OFDM are compared to demonstrate the strength of OFDM in multipath channels. The bit error rate and the number of error bits are calculated during each test on the system. Two simulations of OFDM are developed with inter modulation QPSK or 16-QAM with Reed Solomon Coding are using to correct errors of transmitted data.
