Performance Analysis of Decode and Forward Incremental Relaying in the Presence of Multiple Sources of Interference

This article studies the performance of Decode and Forward Incremental Relaying (DF-IR) in the presence of multiple dissimilar sources of Co-Channel Interference (CCI) at both, the relay and the destination. In particular, we consider the case where all links experience flat Rayleigh fading with K_r and K_d sources of CCI affecting the relay and the destination, respectively. The performance is studied in terms of three performance metrics, the normalized average spectral efficiency, the outage probability, and the error probability. The derived results unveil the incurred losses due to CCI. The accuracy of these results were verified using intensive Monte Carlo simulations.
