Multiantenna-Assisted Wideband Spectrum Sensing Based on Sub-Nyquist Sampling

Abstract: We consider the problem of wideband spectrum sensing, where a multi-antenna secondary user (SU) attempts to identify the frequency locations of a number of single-antenna primary users (PUs) ...

Wideband Rapid Interferer Detector Exploiting Compressed Sampling With a Quadrature Analog-to-Information Converter

Abstract: We introduce a rapid interferer detector that uses compressed sampling (CS) with a quadrature analog-to-information converter (QAIC). By exploiting bandpass CS, a blind sub-Nyquist sampling ...
