摘要
VSAT卫星通信系统是卫星通信领域中的一个重要应用。根据无线突发信道的特点,提出了一种交织器和前向纠错卷积码结合的差错控制方案。仿真结果表明,该方案可以提高抗误码性能,且使用m序列生成的伪随机交织器性能好于矩阵交织器。
VSAT （Very Small Aperture Terminal） satellite communication system is an important application in satellite communication area. Based on the characteristics of wireless burst channels, an error control architecture with the interleaver and FEC （ Forward Error Control） convolution code is proposed. The simulation resuits show that the proposed scheme may advance the capability of anti- burst error, and the pseudo- random interleaver using m- sequence generator interleaver has better performance than the matrixinter interleaver.
