USRP stands for Universal Software Radio Peripheral. It is a type of software-defined radio (SDR) platform developed by Ettus Research, a subsidiary of National Instruments. The USRP devices are used for a wide range of applications related to wireless communication, including research, development, prototyping, and education.
USRP devices consist of a hardware front-end and a software framework that enables flexible and programmable radio functionality. The hardware front end consists of analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) that interface with antennas and other RF components. The software framework allows users to control the radio parameters, such as frequency, modulation, and signal processing, using software-defined radio techniques.
USRP devices are popular among researchers, hobbyists, and professionals working in the field of wireless communication and signal processing. They provide a versatile and cost-effective solution for implementing various wireless systems, such as cellular networks, Wi-Fi, software-defined radios, cognitive radios, and many more.
