Description/Abstract

In this paper, we consider the co-channel interference mitigation capability of ?xed relay aided wireless systems, where the relays are linked to the base station using realistic imperfect optical ?bre. Three interference mitigation techniques are investigated, namely an appealing reduced-power transmission technique, the classic eigen-beamforming arrangement and their hybrid. The cellular model of Shamai and Wyner is used in conjunction with Fractional Frequency Reuse (FFR) and the tradeoffs between the cell-edge throughput and cell-centre throughput are characterised for the three interference mitigation techniques employed. Our simulation results demonstrate that the combination of the reduced-power transmission and the eigen-beamforming technique is capable of improving the achievable throughput for the MSs roaming close to the cell-edge without sacri?sing the throughput of the cell-centre MSs.
