Abstract :
In this paper, a new design of a MAP decoder suitable for ASIC is explained. Quantization of the inputs to the chip is studied and a better quantization with minimum possible number of bits and reliable bit error rate (BER) is chosen for each input based on the simulation results. Max-Log-MAP algorithm used for this purpose is a good compromise between performance and complexity.
