Abstract

This paper presents a design methodology of a concatenated coding system. The system is with rate 1/2 convolutional code and NASA standard RS(255,223) code. The decoder for convolutional code is the Viterbi decoder and is designed with different values of quantization levels. An interleaver and deinterleaver between the two codes with different depth are also included. Simulation results of bit error rate (BER) for the concatenated system and for a certain depth of interleaver are given. The obtained results are compared with the given in NASA/ESA system and good agreement is shown. Keywords- Concatenated system, Reed-Solomon code, Convolutional code, Bit Error Rate.
