摘要

在简要介绍DVB接收系统基本结构的基础上

分析了DVB-S标准下数字卫星接收机中可变码率的QPSK解调和FEC方式的差错控制技术.最后结合自行开发的DVB数字卫星接收机对包含解调与FEC功能的两种集成电路芯片作了比较.

Abstract

Based on a brief discussion of the basic structure of the DVB receiver

this paper analyses the variable rate QPSK demodulation and FEC error correction in the digital satellite receiver and compares two types of integrated circulation.
