文中首先介绍了分组级FEC的概念和分类,然后指出了其常用编码技术的方式及原理,最后根据所给定的PSM N信道模型,在一定条件下通过比较卫星组播系统中基于RSE、卷积码两种编码技术下分组级FEC的性能,得出了一些有用的结论。
Firstly, the concept and classification of packet-level FEC are introduced. Then, the ways and principles of common coding techniques are pointed out. Finally, according to given PSM N channel model, under certain conditions, Plot code two kinds of encoding technology under the performance of packet-level FEC, reached some useful conclusions.
