Abstract :
As shown in the literature, the performance of bit-interleaved coded modulation systems (BICM-ID) depends on the binary sequences mapping to constellation symbols. In this paper, we present a new multidimensional mapping for multi-input multi-output communication systems employing BICM-ID over fast fading channel. To introduce the optimized mapping, cost function is derived based on upper bound on the pairwise error probability over fast fading. Analytical and simulation results show that the optimized mapping outperforms the conventional mapping, and other proposed mappings.
