What is USRP in GNU Radio?
The USRP Source Block is used to stream samples from a USRP device (i.e. act as the receiver). There is no need to use a Throttle block when a hardware source like a USRP Source is used, because the USRP acts as the throttle. There are two methods of setting parameters and adjusting them while running.
How does a Usrp work?
Following a common SDR architecture, USRP hardware implements a direct conversion analog front end with high-speed analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) featuring a fixed-personality FPGA for the digital downconversion (DDC) and digital upconversion (DUC) steps.
What does GNU Radio do?
GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment.
What is uhd GNU Radio?
uhd. Provides source and sink blocks to interface with the UHD library. Used to send and receive data between the Ettus Research, LLC product line.
