基于FPGA的多路卫星信号处理系统的设计实现

卫星通信是当前重要的通信手段之一。针对原有单路解调器的不足，本文提出利用软件无线电思想，通过FPGA构建一种多路卫星信号处理系统。论述了数字下变频（DDC）、解调、数据通路等关键点的设计思路。最终实现的系统可同时处理八路卫星信号，并通过实验验证，完全达到设计预期。并且该系统具有灵活性、可扩展性等多种优势，有良好的应用前景。

Multichannel Satel ite Signal Processing System Based on FPGA

satel ites communication is one of the most usage communication . This paper based on software radio ,it designs a multichannel satellite signal processing system based on FPGA. Mainly introduced the system structure、digtal down conversion（DDC） and demodulation method. The results of experiments show that this system can processing eight channel satel ite signal and performance almost equal to hardware demodulators,but the system has more flexibility and expansibility.
