摘要
从理论上对不同映射方式下的BICM-ID系统在Awgn信道中的性能进行分析和估计;具体通过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。对BICM-ID与其他编码调制方式(TTCM,BICM)的性能进行了比较。仿真结果和理论分析吻合,在Awgn信道中,SP映射取得了最好的性能增益。
In this paper,we first theoretically analyze and evaluate the performance of BICM-ID with different labeling maps in Awgn,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,in Awgn channels,SP labeling provides the best BER performance.At last,we compare the performance of BICM-ID with other coded modulation schemes（TTCM,BICM）.
