| 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。

| Abstract: | 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. |
