Abstract

The performance of a serially concatenated system which includes a channel with memory precoded by a precoder as a rate one inner coder is presented. The effect of different precoders on the maximum likelihood bit error performance is analyzed. The precoder weight gain is identified through a union bound analysis. It is shown that the choice of precoders is critical for a given channel to achieve a good bit error rate performance. Several important design considerations for the choice of precoders are derived based on analysis and these are confirmed through simulations with iterative decoding algorithm
