Exact Outage Probability of Underlay Cognitive Cooperative Networks Over Rayleigh Fading Channels
Khuong, Van Ho Our contribution in this paper is the derivation of an exact closed-form outage probability formula for underlay cognitive cooperative networks operated over Rayleigh fad-ing channels. The derivation considers the correlation among received signal-to-noise ratios, two critical constraints (interference power constraint and maximum transmit power con-straint), and non identically distributed (i.d.) channels. The derived formula is corroborated by Monte Carlo simulations and is served as an useful and effective tool to evaluate the performance behavior of underlay cognitive cooperative networks without time-consuming simulations under different operation parameters. Numerical results illustrate that under-lay cognitive cooperative networks suffer the outage saturation phenomenon for a given maximum interference power level.
