A cooperative compressive sensing scheme for power spectrum reconstruction

Compress sensing (CS) for power spectrum reconstruction (PSR) enables precise and efficient spectrum sensing in cognitive radio networks. Existing CS schemes mainly focus on reconstruction of the original signal, and thus are not appropriate for PSR reconstruction. To counteract this drawback, this letter proposed a cooperative scheme of CS for PSR named decorrelation scheme. A PSR model for cooperative CS is deduced. Simulation results verify the effectiveness of the proposed scheme.
