Cognitive Radio Capability for Software Defined Radios

U.S. Forces face unique spectrum access issues in each country in which they operate, due to competing civilian or government users of national spectrum. Coalition and allied operations are even more complex to manage, and severely limit the U.S. ability to fully exploit its superiority and investment in information technology. DSA a software application capable of running in real-time on a JTRS radio; monitor and characterize the Radio Frequency (RF) spectrum that is in use in a local area. The Soldier Radio Waveform (SRW) requires a wideband, multi-frequency environment to enhance network scalability and deliver broadband communications. DSA as a software upgrade to SRW delivers spectrum access to SRW. Applications that are enhanced by DSA-enabled SRW include tele-operations for tele-operations and solider communications. DSA enables SRW to use commercial and DoD spectrum both CONUS and OCONUS through the automation of coordinated spectrum rules and host nation agreements. This project teams ITT, the SRW developer, and SSC, the pioneer of DSA under DARPA XG, and to design and simulate a DSA implementation for JTRS SRW.
