Performance Analysis for a Two-Ring Distributed MIMO-OFDM System
Distributed MIMO technology is an effective way of dealing with the inter-cell interference problem in single frequency wireless communication networks. This paper studies the generic channel capacity formula for a distributed MIMOOFDM system. A practical two-ring STBC distributed MIMOOFDM transmission scheme is introduced. The cell throughput formula for this distributed scheme is derived. The impact of inner cell radius on cell throughput performance is analyzed for a multi-cell simulation model. From simulation results, we show that the two-ring distributed scheme can effectively mitigate intercell interference and provide good radio propagation channel quality, particularly for users at cells boundary. Moreover, we show that, with proper inner cell radius, the two-ring distributed MIMO-OFDM scheme can achieve significant cell throughput gain compared with that of conventional centralized MIMOOFDM scheme.
