The performance of a multicell wireless network is often limited by intercell interference. This paper considers the use of common-private message splitting at the transmitter and common-message decoding at the receiver for intercell interference mitigation. For a downlink multicell system with multiple antennas at the base-stations and single antenna at the mobiles, we utilize a heuristic SDP-relaxation-based...
In a conventional wireless cellular system, signal processing is performed on a per-cell basis; out-of-cell interference is treated as background noise. This paper considers the benefit of coordinating base-stations across multiple cells in a multi-antenna beamforming system, where multiple base-stations may jointly optimize their respective beamformers to improve the overall system performance. This...
