Cognitive Radio Spectrum Management and Waveform Adaptation for Advanced Wideband Space Communication Systems

ABSTRACT: We analyze approaches to adaptively avoid hostile attack to satellite communications by applying a combined approach of game-theory research, dynamic spectrum access (DSA), policy-based resource management controls and wideband sensing. We analyze the impact of game theory to influence adaptive parameters (power, sensing threshold, frequency, network changes) and avoid attack. We study the evolution of DSA to adaptively control addition parameters at the PHY, MAC and Network layers. We develop analysis and spectrum management reports as part of the Phase I results. BENEFIT: Improve satellite communications in the presence of RF interference from jamming and non-intentional sources. We provide a 10X improvement in spectrum access. We enable wideband sensing and spectrum access. We adapt to jamming sources and hostile attacks (primary user emulation, spectrum herding and denial of service etc). We enable satellites to maintain mission critical communications while defending against attack.
