Abstract :
This paper investigates the opportunistic source-pair selection (OSPS) strategy for the co-channel interference challenge in multiuser amplify-and-forward based bi-directional wireless relaying networks. The method relies upon selection of the appropriate source-pair node among N available source-pair nodes based on each source pair´s maximum sum capacity. According to the simulation results, the OSPS strategy, besides achieving the near optimal solution for the co-channel interference challenge, and if the number of the user pair increases, also achieves multiuser diversity order by selecting the maximum sum-capacity user-pair in each time slot.
