Spectrum Sensing for Cognitive Radios With Unknown Noise Variance and Time-variant Fading Channels
The unknown noise variance and time-variant fading channels make the spectrum sensing design a challenging task for cognitive radios. Most existing sensing methods suffer from the information uncertainty and can hardly acquire promising performances in the adverse situations. To address this challen...
