Opportunistic beamforming is a promising technique for downlink channels in cellular systems. When opportunistic beamforming is to support multiple users at a time, it is important to form multiple beams with as little interference as possible. In the conventional approach with limited feedback of channel state information from users, the best beamforming matrix can be selected from a set of multiple...
Multi-cell cooperative processing (MCP) is well acknowledged for significantly improving spectral efficiency and fairness amongst users. Nevertheless MCP comes together with some shortcomings which have also been recognised. Cooperating Base Stations (BSs) need to be inter-connected via a Control Unit (CU) which gathers channel state information (CSI). CU is the entity responsible for performing MS...
Coordinating the reception and transmission of signals across spatially distributed base stations has been shown to improve sum-rate performance by mitigating the effects of intercell interference in Multiple-Input-Multiple-Output (MIMO) cellular networks. Relying on recent results on the freeness of certain non-Gaussian random matrices, we provide an information theoretic analysis of cooperative...
