摘　　要：针对实际信号接收系统的开发受硬件限制和可扩展性差等问题,基于软件无线电的思想,通过VC与Matlab混合编程,设计并实现了一套虚拟数字接收机系统,主要完成了对接收信号的正交分解、下变频、信号特征提取、信号解调。实际应用表明,其结果对实际数字化接收系统的底层开发和扩展研究具有理论指导作用。To solve the problem that the development of real signal receiving system is restricted to the hardware and bad expansibility, a virtual receiver system based on the idea of software radio was designed and implemented by VC and Matlab. The main function of the program includes I/Q conversion, digital downeonversion, signal feature extraction, signal demodulation. The results of the practical application of the virtual receiver can give theoretical guidance to the basal development and extend the research of real digital receiving system.
