Outage Probability of Interference-Limited Amplify-and-Forward Relaying with Partial Relay Selection
Sung‐il Kim, Jun Heo · 2011
The outage probability of dual-hop amplify-and- forward (AF) relaying scheme with partial relay selection is derived when the multiple interferences affect on the relay nodes. In contrast to the previous works, we focus on analyzing the effect of multiple interferences which make the transmission channel degraded. Following the partial relay selection policy, the best source to relay path is selected based on the comparisons of signal-to-interference and noise ratio (SINR) among all source to relay paths. An exact expression of outage probability is presented and simulation results are also presented for the validity of the analytical result. This result shows the effect of multiple interferences on cooperative AF relaying system in multicell environment.
