【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 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...

Software defined radios have arrived, and FlexRadio is leading the charge. We are on a mission to change commercial and amateur radio.
An SDR-based platform can also reduce the high development costs of a full new ASIC-based solution. But what is really meant by software defined radio? It is not only a system on a chip (SoC) radio receiver with "software inside." This approach is already state of the art. Modern ...
Ettus Research specializes in software defined radio (SDR) systems. The USRP platform addresses a wide range of RF applications from DC to 6 GHz.
4, after the chip holding the device had undergone several manipulations. Data in Fig. 6a, b are obtained using a 0 dBm, 10 MHz signal at the output of SDRLab that is employed as a clock for all instruments. Data in Fig. 6c, d are obtained using a different type of SDRlab ...
RTL-SDR is a popular, low-cost hardware that can receive wireless signals. The RTL-SDR dongle features the Realtek RTL2832U chip, which can be used to acquire and sample RF signals transmitted in the frequency range 25MHz to 1.75GHz. ...
How we Picked the Best Software-defined Radio We looked for a wide range of SDRs in four different price ranges: $50, $100, $300 and $1000. While there are a number of factors that can be considered when picking an SDR, the three main considerations are Hardware specifications, Community...
A software-defined radio (SDR) system is a radio communication system that uses software to process various signals (modulation, demodulation, decoding, etc.) in lieu of the traditional hardware components that are generally made for those dedicated tasks. It is mostly used in mobile communications...
