ADAPTIVE DOUBLE THRESHOLD ENERGY TECHNIQUE OF SPECTRUM SENSING TECHNIQUES FOR WIRELESS COGNITIVE RADIO NETWORKS

Abstract

Wireless communication should mainly tackle the issue if spectrum under utilization, it is overcome by
this cognitive radio method. Sensing of spectrum is the very essential and foremost aspect in cognitive
radio. There are various algorithms are available in sensing the spectrum due of the easy implementation
of the energy detection method is used widely, as it will not consider any prior information about primary
user (PU). In low Signal Noise Ratio portion, the energy detectors will progressively worse its
performance. In order of reaching increased reliability of the decision the Cooperative Spectrum Sensing
with dual threshold is presented
