Software-defined radio (SDR) is a radio communication system where components traditionally implemented in analog hardware, such as mixers, filters, and modulators, are instead implemented using software on a personal computer or embedded system[1]. In an SDR, the properties of the radio, such as...
High Quality Software-Defined Radio (SDR) receivers from DC to Daylight for Governments, Professionals, Academics and Hobbyists.
Software-defined radio (SDR) is a radio systemwhere 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 ...
A system for providing software defined radio on a mobile device includes a hardware portion including an antenna and an interface configured to connect to the mobile device; a software portion configured for execution on the mobile device, the software portion configured to receive and process RF ...
Ettus Research specializes in software defined radio (SDR) systems. The USRP platform addresses a wide range of RF applications from DC to 6 GHz.
The Software-Defined Radio (SDR) was the first communication system entity for which hardware became enriched with software. In the beginning of SDR, two main concepts were considered, reuse of hardware components and flexible control of components. One example for the first concept is the reuse ...
【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。
