Cognitive Radio Capability for Software Defined Radios

Shared Spectrum Company (SSC) and Boeing Integrated Defense Systems build on their work on the DARPA XG, WNaN and JTRS programs to incorporate adaptive cognitive radio capabilities into the Joint Tactical Radio System GMR Wideband Networking Waveform (WNW). We perform trade studies to determine the best approach to porting DSA software, develop detailed DSA requirements, design an open API architecture for DSA portability, study software modules for DSA sensing and detection requirements, and study red/black issues related to DSA implementation in the GMR. SSC delivers an Initial Open Architecture API design document, WNW DSA Spectrum Access Rules and CONOPs Reports, a Spectrum Stakeholders Report, and a WNW Detailed DSA Implementation Report proving how DSA will integrate into the GMR Wideband Network Waveform. We then port the DSA software to the JSR platform with support from SPAWARS, Assured Communications and Blue Collar Objects. We conduct a laboratory and field demonstration of the DSA enabled JSR radio. SSC has already ported its DSA software to 5 different radio platforms, and extensively field-tested it under the DARPA XG program, and possesses the depth of experience to study and design a DSA solution for WNW. This project formalizes the transition of DSA technology first demonstrated in JTRS-certified radios from Thales and Harris into an open, standard architecture for delivery into the JTRS GRM and JTRS waveform library, thus enabling efficient transition of DSA techniques to all JTRS radios.
