The impact of antenna diversity on the capacity of wireless communication systems
TL;DR: For a broad class of interference-dominated wireless systems including mobile, personal communications, and wireless PBX/LAN networks, the authors show that a significant increase in system capacity can be achieved by the use of spatial diversity (multiple antennas), and optimum combining.
Journal ArticleDOI
Transmit beamforming and power control for cellular wireless systems
TL;DR: Joint power control and beamforming schemes are proposed for cellular systems where adaptive arrays are used only at base stations and the performances of these algorithms are compared with previously proposed algorithms through numerical studies.
Journal ArticleDOI
Optimum Combining in Digital Mobile Radio with Cochannel Interference
TL;DR: Analytical and computer simulation techniques are used to determine the performance of optimum combining when the received desired and interfering signals are subject to Rayleigh fading, and results show that optimum combining is significantly better than maximal ratio combining even when the number of interferers is greater than thenumber of antennas.

Joint optimal power control and beamforming in wireless networks using antenna arrays
TL;DR: This work considers a system with beamforming capabilities in the receiver, and power control, and proposes an iterative algorithm to jointly update the transmission powers and the beamformer weights that converges to the jointly optimal beamforming and transmission power vector.
