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 circuit chips applied in the DVB receiver made by ourselves.
