다중 셀 MIMO 하향채널의 셀 에지 SINR = Cell Edge SINR of Multi-cell MIMO Downlink Channel

다국어 초록 (Multilingual Abstract)

In this paper, we consider 19 cells with the two tiers for polar-rectangular coordinates (PRCs) andprovide the cell edge performance of cellular networks based on distance from cell center i.e., BS (base station).
When FFR is applied(or adopted) to cell edge, it is expected that BS cooperation, or a coordinated multipoint(CoMP) multiple access strategy will further improve the system performance. We proposed a new method toevaluate the sum rate capacity of the MIMO DC of multicell system. We improve the performance of cell edgeusers for intercell interference cancelation in cooperative downlink multicell systems. Simulation results show thatthe proposed scheme outperforms the reference schemes, in terms of cell edge SINR (signal-to-interference-noiseratio) with a minimal impact on the network path loss exponent. We show 13 dB improvements in cell-edge SINRby using reuse of three relative to reuse of one. BS cooperation has been proposed to mitigate the cell edge effect.
