Due to the frequency reuse,the outage performance of the interference-limited two-hop multiple access-channel (TH-MAC) has become one of the problems to be solved.With interference-limited destination,the outage probability of the amplify-and-forward (AF) TH-MAC is derived in closed form.Firstly,the outage probability is divided into two parts:one is the probability that an outage happens at the relay;the other is the probability that outage does not happen at the relay,but happens at the destination.Then,based on rational approximation for the second part of the outage probability,a closed form outage probability is derived for the channel,and it provides a theoretical framework for the practical system design.Numerical results show that the approximation fits well with the Monte Carlo results,which validates the accuracy of the approximation.
