软件无线电是将硬件作为无线通信的基本通用平台,用软件实现尽可能多的无线通信功能.它被视为继模拟和数字技术后的又一次电子技术革命.未来理想的网络将是一个统一网络,这个网络会容纳多种协议与标准,将对各种传播环境与物理介质进行适应,还有更加开放的接口需要其来提供,所以软件无线电将会有更加广阔的发展前景.%Software radio takes hardware as the basic common platform of wireless communications, and uses software to achieve wireless communications as much as possible. It is seen as another revolution in electronic technology following the analog and digital technology. Ideal future network will be a unified network which will accommodate a variety of protocols and standards, will adapt to the mass media and physical environment, as well as will provide a more open interface requires, so software radio will have a more broad development prospect.
