Abstract

In this letter, the exact form of the outage probability for opportunistic amplify-and-forward (AF) partial relay selection scheme in interference-limited environment is derived. It is assumed that multiple interferers affect only on the relays due to the multicell environment of wireless networks. Analysis in this paper can be an efficient technique for investigating the effect of interference in cooperative AF relaying on the outage probability. We confirm that our analytical results match the simulation results perfectly on all the ranges of signal-to-noise ratio (SNR).
