基于PCI和LVDS的接收机测试源设计

Design of Testing Source for Digital Receiver Based on PCI and LVDS

本文基于PCI和低压差分器件LVDS,给出了适用于数字接收机试验平台测试的模拟测试信号源的设计方法和设计电路。通过良好的软件和PCI的结构设计,使该设计具有了良好的通用性。同时采用新的LVDS器件,使该设计能够满足宽数据率的要求。通过应用层程序修改,该模拟测试信号源可以适用于通信、雷达、音频等数字接收机的算法仿真测试工作,具有良好的通用性。

A flexible testing source for the digital receiver testing bed is implemented. The hardware circuit design of the key modules and the software design are described in this paper. The PCI and the LVDS are carefully designed to satisfy the flexible and high data througput. The layered software design is the key advantage for system applicability. By modify the application software, this testing source can be used in the radar, communication or acoustics receiver system for algrithm simulation and testing.
