摘要：In this Paper, a simulation of COFDM (Coded OFDM) over Multipath Fading channel, using R-S (15/11, Double error correcting) Code is done. Coherent QPSK is used to modulate the data and a training based channel estimator is implemented. In the present work it is observed the perfor mance of RS code and chooses the effective parameters in the AWGN Channel that can improve COFDM system. Evaluation of Symbol Error Rate (SER) performance for R-S code as a function of code r ate and block size can be tested .This testing can be applied to single carrier system with AWGN channel model using coherent Quadrature phase shift keying modulation (QPSK) technique. A new scheme may evaluate and compare all results with conventional performances for every step, and consequently to clear out the improvements stem from applying R-S codes. SER performance over AWGN channels is done respectively
