摘　　要：简要介绍了移动电视传输标准CMMB中RS(里德-索罗门)编码的特点。采用Matlab进行算法验证,并用FPGA实现。字节交织使用乒乓流水线结构,缩短了等待时间。针对k=176设计出节约成本的编码器。提出利用VGA接口获取FPGA验证数据源,使用"编码-解码-重现"的模式对RS编码器充分验证。The characteristics of RS code on CMMB is introduced,and Matlab is used to verify the algorithm which is realized based on FPGA.Byte interleaving is realized by using the ping-pong pipeline,which can reduce the time for waiting.According to k=176,a new cost-saving RS encoder is designed.In this design,the VGA interface is used to obtain the source data of verification on FPGA.And the RS encoder designed is fully verified by using the mode of encoding-decoding-reproducing.
