摘　　要：采用便于实现并性能较好的BM算法,结合流水线技术,设计并实现了符合CMMB标准的时域译码器。实验证明,该译码器具有多码率复用、控制简单灵活、面积小、资源耗用少、工作速率高、数据吞吐量大等优点。In this paper, the implementation of a time domain and China Mobile Multimedia Broadcasting （CMMB） conformed to RS decoder is discussed. This decoder uses a hardware structure to realize and BM algorithm with high performance and also the pipelining technology. The experimental results prove that the decoder has the advantages of easy-control, small area, small re- source consumption, high working speed and large data throughput.
