Subspace-based joint multiband detection for wideband spectrum sensing
Doris Bao, Pasquale Daponte, Luca De Vito, Sergio Rapuano · 2012
The paper presents a new method for the simultaneous detection of signals occupying separate portions of an observed wide frequency band. The method is based on the subspace decomposition of the covariance matrix of the observed signal. The proposed method does not rely on the knowledge of the noise power and gives good results in terms of correct detections and false alarm rate, even for low SNR values.
