摘要
针对DVB-S2标准中BCH码的特殊性,对超长码字下的BCH编/译码器的参数配置方法和并行实现结构进行了深入研究。以第二代数字视频广播标准DVB-S2中BCH码的应用特点为需求,以较小的硬件资源实现了一种21种码字参数可配置的并行BCH编/译码器。设计的BCH编/译码器具有较高的数据吞吐率,能够满足DVB-S2各种应用需求。
For the particularity of BCH code in DVB-S2 standard, the parameter configuration method and parallel imple- mentation structure of BCH encoder/decoder in overlength codon are studied in-depth. Based on the application characteristics of BCH code in the second generation DVB-S2 standard, a parallel BCH encoder/decoder of 21 codon configurable parameters was realized with less hardware resources. The designed BCH encoder/decoder has high data throughput, and can meet various appli- cation requirements in DVB-S2 standard.
