Outage performance for amplify‐and‐forward two‐hop multiple‐access channel with noisy relay and interference‐limited destination

Abstract

The common outage performance of an amplify-and-forward two-hop two-user channel is studied in the presence of multiple independent interferers at the destination. First, the exact integral form expression of the common outage probability is derived. Then, in order to decrease the computation complexity, a closed-form approximation of the common outage probability is derived. Finally, the asymptotic analysis is performed based on the approximation expression. Numerical results demonstrate that the integral form of the common outage probability, the corresponding approximation and the asymptotic results match well with the Monte Carlo simulations.
