摘　　要：卫星通信作为一种无线应急通信手段原来越受到人们的重视,近年来随着卫星技术的发展卫星通信向小型化和高频段方向不断发展,工作于Ka频段或者更高频段的卫星通信系统逐步得到发展和逐步使用。在此通过卫星通信系统中不同级联编码在Ka频段信道模型的基础上,对几种级联编码方式进行了分析研究和LabVIEW仿真。通过仿真可以得出级联码系统在高频段上可以获得更低的误码率和更好的性能。As a best emergency way, the satellite communication is widely used in many countries, and has attracted more and more people＇s attention. In recent years, with the increasing demand for the satellite communication and the rapid develop- ment of satellite communication technology, the miniaturization and high frequency are the developing trend for the satellite communication. The satellite communication equipment works in the Ka band or higher frequency band. Based on the channel models of different cascading coding in the satellite communication at ka-band, some cascading coding modes are analyzed and emulated with LabVIEW software. The simulation result indicates that the cascading coding mode can achieve lower BER and better performance at high- frequency band.
