基于软件无线电结构的扩频通信接收机中频系统数字化方案研究

An IF Digitalization Scheme in the Spread Spectrum Receiver With Software Radio Architecture

介绍了通用的软件无线电系统的基本结构，着重提出了一种基于软件无线电结构的直接扩频系统接收机中频系统的数字化实现方案，并对其工作原理进行了详尽的分析。采用这种方案可提高现有扩频通信系统的数字化、软件化、模块化程度，从而有利于提高扩频通信系统的有效性与可靠性。

Introducing the canonical software radio architecture briefly, we present a novel scheme of IF digitalization based on the software radio architecture, used in a direct sequence spread spectrum communication receiver, and its more detailed analysis, in order for improving the extent of digitalization, softwarization, modularization in the available spread spectrum communication system to enhance greatly its effectiveness and reliability.
