Sub-Nyquist Cognitive Radio System

We demonstrate of a real-time sub-Nyquist sampling and reconstruction system, based on prototype hardware and an embedded proprietary card, the subNyquist Cognitive Radio setup (CogRadio). Our system detects the support and reconstructs a wide-band sparse signals with arbitrary support from sub-Nyquist samples. This process takes place in real-time. The CogRadio system is shown to comply with cognitive radios requirements.
