Coordinated Beamforming for MISO Interference Channel: Complexity Analysis and Efficient Algorithms

In a cellular wireless system, users located at cell edges often suffer significant out-of-cell interference. Assuming each base station is equipped with multiple antennas, we can model this scenario as a multiple-input single-output (MISO) interference channel. In this paper we consider a coordinat...
