    Abstract :

    In this paper, we conduct performance comparison of RS-RSC concatenated system with BCH-RSC concatenated system. Two models of serially concatenated codes are simulated and tested over AWGN channel using Matlab simulations. The first model uses Reed-Solomon (RS) code as outer encoder and Recursive convolution code (RSC) as inner one & decoding is performed by concatenation of Viterbi decoder & Berklelamp-Massey decoder. The second model uses Concatenation of BCH code as outer encoder and RSC code as inner encoder. We show that the performance of BCH-RSC concatenated code is better than RS-RSC concatenated code in terms of bit error rate (BER).
