| 摘 要： | 设计了一种应用于中继卫星地面系统的多模式数传及测距接收机
。在本设计中，以软件无线电理论作为指导思想，采用了VLSI可编程芯片作为算法主要实现
器件，
在一块CPCI标准6U板卡中集成了两路相互独立的信号通道，能够分别接收两路信息速率在10
Mbit/s以下的调制、编码、扩频方式均不相同的返向信号，并利用扩频码提取距离数据。
调制方式包括
BPSK、QPSK、SQPSK、UQPSK，编码方式包括RS、卷积、RS+卷积。基于此，接收机还可应用
于其它多通道、多模式的数传系统中。

| Abstract: | A multi-mode data transmission and range receiver is designed for the ground sys
tem of TDRSS(Tracking and Data Relay Satellite System). Based on SDR(Software De
fined Radio) theory, VLSI(Very Large Scale Integrated) programmable chip is used
as the main device to realize algorithm. Two i
ndependent signal channels are integrated on a 6U standard CPCI interface card,
which can receive two channels return signal with rate below 10Mbit/s and differ
ent modulation, coding and spectrum spreading modes, respectively, and the dista
nce can be extracted from the PN code. The modulation modes include RS, convolu
t
ion and RS+convolution. Based on the characteristics, this receiver can also be
used to other multi-channel and multi-mode data transmission systems. |
