    • Compressed wideband spectrum sensing with correlated subband occupancy in multi-antenna cognitive radios 

      Monfared, Shaghayegh S. M.; Taherpour, Abbas; Khattab, Tamer (2012 , Conference Paper)
      In this paper, we investigate the use of multiple antennas at the cognitive radio receiver for improved wideband spectrum sensing and exploit compressed sensing to reduce the extremely high sampling rate of wideband signal. ...

    • Time-frequency compressed spectrum sensing in cognitive radios 

      Monfared, Shaghayegh S.M.; Taherpour, Abbas; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2013 , Conference Paper)
      In this paper, we investigate the use of time-frequency analysis for improvement of spectrum sensing in cognitive radios and exploit compressed sensing (sampling) to reduce the extremely high sampling rate of signal in ...
