The Impact of CSI and Power Allocation on Relay Channel Capacity and Cooperation Strategies
Capacity gain from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. Under quasi-static channels, when all nodes...

Distributed Multi-Cell Zero-Forcing Beamforming in Cellular Downlink Channels
Abstract— For a multiple-input single-output (MISO) downlink channel with ¢ transmit antennas, it has been recently proved that zero-forcing beamforming (ZFBF) to a subset of (a...
