摘　　要：文中提出一种基于2-FSK/4-PSK调制的比特交织编码调制系统(BICM)。理论分析和计算机仿真表明无论在AWGN信道或是Rayleigh衰落信道下,通过合理控制2-FSK/4-PSK调制,BICM系统的性能都有所提高,且在衰落信道下新系统将达到基于8PSK调制的BICM-ID系统多次迭代的效果。A novel bit-interleaved coded modulation （BICM） system based on 2-FSK/4-PSK modulation is proposed in this paper. Comparative study is done through theoretical analysis and computer simulation. The results show that the new system outperforms the normal one by appropriate designing of 2-FSK/4-PSK modulation under both AWGN channel and Rayleigh fading channel. And the new will match up to many times iteration of BICM-ID system based on 8PSK modulation.
