This study investigates the opportunistic source‐pair selection (OSPS) strategy for the intercell interference (ICI) challenge in multi‐user amplify‐and‐forward‐based bi‐directional wireless relaying networks. The method relies on selection of an appropriate SP node among N available SP nodes based on each SP's maximum sum capacity (SC). According to analytical, asymptotic and Monte Carlo simulation results, the OSPS strategy, besides achieving the near‐optimal solution for the ICI challenge, if the number of the user‐pair increases, also achieves multi‐user diversity gain by selecting the maximum SC user‐pair in each time slot. Moreover, the SC‐based user‐pair selection method outperforms the simultaneous transmission model and the max–min‐based user‐pair selection method in such a system model.
