DVB-S接收系统的结构及其性能分析

The Structure and Performance of DVB-S Receiving System

介绍DVB- S数字卫星综合接收解码器的结构, 给出其抗噪声性能的分析结果, 由此得到一种在给定地面接收系统优值( G/ T)e下, 推算出系统误比特率Pb的方法.

This paper introduces the structure of DVB-S Digital Satellite Integrated Receiving Decoder and analyzes its performance of resisting noise.The analytical results show that the Error Bit Rate ( P b ) of the receiver can be deduced if the parameter of receiving station( G/T) e is given.
