摘　　要：本文提出了采用Ⅲ型H-ARQ的BICM-ID系统实现方案。给出了传输协议及组合译码算法,从理论上分析了系统通过率。在Awgn信道和Rayleigh衰落信道下,对分别采用Ⅰ型,Ⅱ型,Ⅲ型H-ARQ的BICM-ID系统通过率进行了仿真比较。结果表明,与采用其他两种类型H-ARQ的BICM-ID系统相比,采用Ⅲ型H-ARQ的BICM-ID系统性能最优。而且,在低信噪比和Rayleigh信道下的优势更加突出。We proposed type Ⅲ H-ARQ utilizing BICM-ID. The retransmission protocol and combing-decode algorithms are described and then the throughput performance is analyzed theoretically. We simulated the throughput of BICM-ID system which uses type Ⅰ, type Ⅱ and type Ⅲ H-ARQ in Awgn and Rayleigh fading channels. The simulation results show that the advantage of type Ⅲ H-ARQ used in BICM-ID can extremely improve the throughtput compared with the other two schemes. Especially, the proposed scheme is more prominent in the range of low SNR in Rayleigh fading channel .
