Sidelobe Suppression for Capon Beamforming with Mainlobe to Sidelobe Power Ratio Maximization
Yipeng Liu, Qun Wan
High sidelobe level is a major disadvantage of the Capon beamforming. To suppress the sidelobe, this paper introduces a mainlobe to sidelobe power ratio constraint to the Capon bea…

Total Variation Minimization Based Compressive Wideband Spectrum Sensing for Cognitive Radios
Yipeng Liu, Qun Wan
Wideband spectrum sensing is a critical component of a functioning cognitive radio system. Its major challenge is the too high sampling rate requirement. Compressive sensing (CS) p…
