Abstract:

 

The performance of communication systems has been developed thanks to the application of the iterative decoding techniques. In this paper, a generalization of parallel concatenated block (GPCB) codes based on RS codes is presented. Simulations are used to look into the effect of different component codes, interleaver sizes and patterns, and the number of iterations. The simulation results show the relevance of the adapted parameters to decode generalized parallel concatenated block codes based on RS codes. The results obtained by using adapted parameters outperform those obtained with empiric parameters.
