Optimization of Spectrum Hole Utilization in Rayleigh Faded Cognitive Radio Networks

Abstract

This paper investigates the optimization of the probability of spectrum hole utilization (PSHU) given minimum sensing error rate in Rayleigh fading channel. An optimal detection threshold is calculated to minimize the sensing error. Analytically it is very complex to solve optimal threshold, so numerically optimal threshold is calculated which gives the minimum sensing error, PSHU can be maximized on an optimal sensing time.
