摘　　要：BICM-ID系统是一种将信道编码和高阶调制相结合的调制方式,这种方法的应用能够不断地提高系统的带宽利用率,以便更好地接近信道容量。为了更有效地提高系统的频带利用率,在BICM-ID系统中可以采用多维映射标识的方法,本文通过对多维映射系统的成对错误概率PEP的分析,介绍了多维映射标识的构成方法,重点介绍了QPSK和8-PSK的四维映射及性能仿真结果。Bit-Interleaved Code Modulation with iterative decoding（BICM-ID） is a technique with combination of coding and high-order modulation.The application of this method can improve system bandwidth utilization continually in order to better approach the system＇s capacity.In order to improve the system bandwidth efficiency more effectively,Multi-Dimensional（MD） labeling map modulation can be used in the BICM-ID system.Based on the analysis to the pairs of error probability（PEP） of MD mapping,the optimal constructing methods of Four-Dimensional mapping of the QPSK and 8-PSK are introduced and the simulation to their performance is presented.
