Adaptive Threshold Control for Energy Detection Based Spectrum Sensing in Cognitive Radios

We study energy detection based spectrum sensing of SU (Secondary User) in cognitive radios. Due to the time varying nature of wireless channels and PU (Primary User) activities, the SINR (Signal to Interference plus Noise Ratio) at the SU receiver changes from slot to slot in a time-slotted system....
