Keywords: cognitive radio primary and cognitive users (PU and CU)energy detector Rayleigh and Rician fading

Abstract

A sensing time optimization was performed by means of cyclic channel sensing. The channel efficiency of the secondary user is chosen as a metric. In detail are considered following cases: deterministic channel without fading, channel with Rayleigh and Rician fading, Gaussian approximation. We have implemented computational works and identified the most essential factors, that impact on channel efficiency.
