A Review: BER Performance Analysis of OFDM system using Reed-Solomon Codes

In this paper, present the performance analysis of the orthogonal frequency-division multiplexing (OFDM) communication system in term of BER (bit error rate) using Reed-Solomon (RS) codes with and without Interleaver (IL) over 16-QAM modulation schemes through AWGN. The RS coding scheme and interleaver has strong ability to correct the burst errors and random errors, and has been broadly used in wireless communication system design. The significance of random interleaver is to improvement the BER performance over other interleaver scheme is proposed. The transmission data is realized with 64-FFT and 64-IFFT technique. The whole MATLAB simulation results show that the RS coded OFDM system with IL scheme performs the better BER as compared to RS coded OFDM system without IL. The code rate of RS encoder also affected the BER performance of OFDM system in both schemes with and without IL. In both proposed simulation system, the BER performance increases with increases the code rate of the system.
