Prediction of Area Capacity in a Multilink MIMO Cellular Network with Guaranteed QoS

Multilink MIMO technique is a promising technology for cellular networks with a guaranteed quality-of-service. It will provide high capacity and wide coverage. The authors evaluated the downlink performance of the multilink MIMO system from the perspective of quality-of-service. The presence of Rayleigh fading, shadowing, and path loss is assumed. To evaluate the proposed system, the authors develop a performance measure for MIMO cellular systems. The measure is ergodic capacity taking into account area coverage. The numerical results show that the area coverage of proposed multilink MIMO system is greatly improved compared with that of the conventional singlelink MIMO system. Using the proposed measure, the authors also find that the multilink MIMO system could achieve high capacity with guaranteed QoS for a wide coverage.
