摘要
从理论上对不同映射方式下的BICM-ID系统在Rayleigh衰落信道中的性能做了分析和估计,通过3种映射方式(SP,SSP,Gray)下BICM-ID系统的性能仿真,对理论分析进行了验证。仿真结果和理论分析吻合,在Rayleigh衰落信道下,SSP映射性能最佳。与其他编码调制方式(TTCM,BICM)的性能相比,在Rayleigh衰落信道下,随着信噪比的增加,BICM-ID性能要优于其他编码调制方式。
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 thooretic 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.
