摘　　要：本文提出了一种DVB-S接收机中符号处理功能的实现方案。采用“二次编码”和特殊的同步搜索及字节恢复电路,不仅使处理时间显著减少,同时硬件资源也得到节省,现已经应用于卫星数字电视接收芯片的设计中。This paper proposes an implementation scheme of symbol-processing in DVB-S receiver. By using 'Secondary Encode' and special sync-searching & byte-recovering circuits, not only the processing time reduces remarkably, but also needs less hardware resource. This scheme has already been applied in the chip design of satellite digital television.
