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.
