目前，软件无线电技术已成为无线电通信领域，特别是军用无线电通信领域的技术热点。随着微电子技术的迅速发展，数字信号处理器等通用可编程器件的运算能力在成倍提高，而价格却成倍下降，这样就使得软件无线电在技术实现及经济成本等方面成为可能。文中详细讨论了软件无线电的体系结构、关键技术及对策。
At present, the software radio technology has become a hot spot in the field of radio communications, especially in the field of military radio communications. With the rapid development of microelectronic technology, the computing power of general-purpose programmable devices such as digital signal processors has doubled while the price has doubled. This makes it possible for software and radio to realize their technologies and their economic costs. The architecture, key technologies and countermeasures of software radio are discussed in detail in this paper.
