A covariance matrix-based spectrum sensing technology exploiting stochastic resonance and filters
Abstract Cognitive radio (CR) is designed to implement dynamical spectrum sharing and reduce the negative effect of spectrum scarcity caused by the exponential increase in the number of wireless devices. CR requires that spectrum sensing should detect licenced signals quickly and accurately and enab...
