摘　　要：软件无线电是一种基于可编程能力强的高速数字信号处理DSP,将通用化、模块化、标准化的硬件单元以总 线方式连接起来,形成一个通用硬件平台,并利用软件加载来定义和实现各种无线通信功能的开放式体系结构。软件无线 电技术的基本思想是在射频端实现信号的数字化,通过可编程的DSP模块完成对数字信号的各种处理,其核心技术有多频 段宽带天线、宽带A/DD/A转换、高速DSP。在军事通信方面,软件无线电以其灵活性、互通性等特点必将引起各国军 用无线电台的根本性变革。Based on programmable high speed DSP, software radio is an open system which connects current, modular, standard hardware units by Bus, forms a current hardware flat roof, and defines and realizes all kinds of wireless communications through loaded software, the basic thought of software radio is carry out signal′s digital, complete the DS′s all kinds of disposal through programmable high speed DSP, its core technology is multifrequency and wideband antenna, wideband A/DD/A converters and high speed DSP. Software radio will probably cause radical revolution of military radio station in all countries characterized by its agility, intercommunication and so on.
