This paper investigates the downlink transmission for cooperative cellular networks with multi-base stations and single mobile station using statistical channel state information at the base stations. We consider a general jointly correlated MIMO channel model. We first propose an optimal transmission scheme to maximize the ergodic sum capacity, which reveals the transmit signals of all base stations...
The paper considers the multiple-access two-hop relay network, due to more practical environment, the source nodes only know the statistical channel state information. We adopt a general jointly-correlated MIMO channel model, which does not require separable spatial correlations at the source nodes and relay node. Based on this model, we firstly derive the closed-form tight upper bound for the ergodic...
