Universal Software Radio Peripheral

Universal Software Radio Peripheral ( USRP ) is a computer hardware from Ettus Research LLC and its parent company National Instruments for the production of telecommunication system software.

Application

The invention comes from Matt Ettus from the USA and is better known under the term "GNU radio". With the USRP for example it is possible to operate a GSM base station in the context of open- BTS project.

Furthermore, it is possible with the USRP operation of synchronized transmission method, because it has a way of clock recovery, for example, an atomic clock. The methods by which the USRP can realize synchronized transmission mode, are ACSB (amplitude companded sideband ) and SyncFM example in the analog FM broadcast range, but also entire frequency networks as a DAB network can be built.
