In this study, the authors consider a two‐way relaying (TWR) system with source terminals and and a relay terminal . They analyse the performance of a fixed‐gain amplify‐and‐forward‐based TWR system over Rayleigh fading channels with co‐channel interference at all the terminals. Expressions are derived for the outage probability of the system at a medium‐to‐high signal‐to‐interference‐plus‐noise ratio (SINR) range. They also obtain the expression for the value of outage floor and use this to optimise relay location and power allocation. Simulation results demonstrate accuracy of the derived expressions in different SINR ranges.
