一款基于软件无线电的多模接收机的设计

软件无线电接收机是基于一个通用可编程硬件平台,通过软件来实现各种通信标准。随着数字处理技术不断进步,理想软件无线电的最终实现成为可能。该文对软件无线电中的关键技术、系统架构、射频信号处理、中频信号A/D处理技术、数字信号多模式处理、数字解调、软件无线电接收机进行探讨,以AM、SSB、CW、FM信号为例,仿真了该设计方案的可行性。

A Multimode Receiver Based on Software Radio Design

The software radio receiver is kinds of corresponding standards through based on software. the ideal software radio becomes into a reality. This a general programmable hardware platform and realizes all With the development of the digital processing technology, paper discusses some issues such as the key technologies, the system architecture, the radio-frequency signal processing, the intermediate frequency signal A/D process- ing technology, the digital signal multi-schema processing, the digital demodulation, the software radio receiv- er. And also, it takes AM, SSB, CW, the FM signal as examples to simulate the design proposal to validate its feasibility.
