本文介绍了基于SDR(软件无线电)的新一代卫星宽带解调器,它由CPCI刀片工控服务器、2块中频变频采集卡及4块解调译码卡组成,本文介绍了其基本原理、结构组成、性能参数,阐述了各板卡的具体设计与实现,并给出了部分性能仿真,最后介绍了实现时的技术难点。 -The main idea of SDR is to construt an open and modularized general platform,to carry out all kinds of functions with software,and locate the wideband A/D nearest from the antenna.In this paper,a new kind of satellite wideband demodulator based on SDR,is introduced,which consists of CPCI slice industrial server,2 cards for intermediate frequency convertion and sampletion and 4 cards for demodulation and decoding. The paper still introduces the fundamental,construction and performance parameter of the demodulator,specifies the design and implement of the cards,and provides several simulations.At last,the difficulties is discussed.
