Research on Performance of BICM-ID Based on Soft-decision in Rayleigh

In this paper,we first theoretically analyze and evaluate the performance of BICM-ID with different labeling maps in Rayleigh channels,then validate the theoretic analysis by simulations of BICM-ID with three labeling maps(SP,SSP,Gray).The simulations are same with the theoretic analysis,SSP labeling has the best performance in Rayleigh fading channel.At last,we compare the performance of BICM-ID with other coded modulation schemes(TTCM,BICM) and the results show that the BICM-ID has better performance than other schemes along with the increasing SNR in the Rayleigh fading channel.
