GNU Radio is a quite capable open source software radio framework. The GNU Radio architecture is based around a set of reconfigurable data sources and data sinks that are connected to form signal processing tool chains. To allow the SSRP to interface with the GNU Radio framework, a SSRP data source module has been developed.
The USRP library has been ported over and high speed data transfers in excess of 40MB/sec have been performed using ported versions of the USRP's fusb code. All library code to support the GNURadio module is in place and an initial RX-only SSRP module for GNURadio is available.
