摘　　要：为了提高国产卫星通信地球站调制解调器信道级联编解码工作数据速率,给出了一种兼容世界卫星通信地球站308/309/310标准(IESS-308/309/310)所有级联编解码技术参数要求的外码设计方法。对加解扰器、RS编解码器、交织解交织器以及同步系统进行了设计与仿真,最高数据率可达50 Mbps。最后给出了系统部分最终测试结果。To improve the concatenated codec dada rate of the homemade satellite communication earth station modems, a new PFGA design method of the outer codec is presented, which is compatible to the International Earth Station Standard 308, 309 and 310. The designs and simulations of scrambler and descrambter, RS coder and decoder, interleaver and deinterleaver, and synchronous subsystem are completed. The data rate of the system can be up to 50 Mbps. Finally, part application test results are given.
