Outage Probability of EGC Receiver Over Composite Fading Channels with Phase Error and Co-channel Interference

ABSTRACT

The outage probability of an arbitrary branch equal gain combining (EGC) receiver with carrier phase error in the presence of co-channel interference in composite generalized gamma (GG) and composite generalized K (K_G) fading environment is derived. Mathematical expressions for the outage probability of the EGC receiver for these fading channels have been obtained. The obtained expressions for the outage probability are numerically evaluated. Numerical results for different degrees of phase errors is plotted with the simulation results. Simulation results closely match with the numerical results.
