【答案】：软件无线电(SDR，SoftwareDefinedRadio)，就是采用数字信号处理技术，在可编程控制的通用硬件平台上，利用软件来定义实现无线终端的各部分功能：包括前端接收、中频处理以及信号的基带处理等。即整个无线终端从高频、中频、基带直到控制协议部分全部由软件编程来完成。
Software-defined radio (SDR) is a radio system where traditional analog components are replaced with digital components and software technologies. In traditional radio systems, a radio was designed entirely in analog and for a specific application. By contrast an SDR can be used to process a wide...
