一种基于软件无线电的中频接收机实现

A kind of IF receiver based on software radio technology

介绍了一种基于软件无线电技术的中频数字接收机的实现方案,它主要由数字正交调谐器和数字科斯塔斯环构成,通过配置不同的软件即可实现不同频带、不同调制类型信号的全数字接收。

This paper discusses a kind of digital receiver based on software radio technology, which is composed of Digital Quadrature Tuner and Digital Costas Loop. With the help of software, the receiver can demo-(dulate) many kinds of modulation signal.
