In cognitive radio (CR), the problem of limited spectral resources is solved by enabling unlicensed systems to opportunistically utilize the unused licensed bands. Compressive Sensing (CS) has been successfully applied to ...

The frequency diversity exhibited by cyclostationary signals is exploited in this paper. A novel rank-1 frequency-domain representation of a digital waveform is proposed to address the generalized likelihood ratio (GLR) ...

As shown by Medard, the capacity of fading channels
with imperfect channel-state information (CSI) can be lowerbounded
by assuming a Gaussian channel input and by treating
the unknown portion of the channel multiplied ...
