摘　　要：论述一种基于软判决反馈迭代译码的比特交织编码调制方案。此方案可以不通过扩展频带来提高通信系统在瑞利信道中的编码增益,有效抵抗无线信道噪声、衰落等干扰。仿真结果表明,比特交织编码调制方案能有效提高系统的接收性能。A bit interleaved coded modulation （BICM） scheme was introduced, with iterative decoding using soft decision feedback. ID, it could yield a better So it is named as BICM with iterative coding communication systems, and resist decoding （BICM-ID）. By using BICMgain over Rayleigh fading chanriels without bandwidth expansion for the noise and fading as well. Simulation results show that the BICMID scheme can effectively improve the receiving performance for communication.
