Distributed Penalty-Based Beamforming Design for Multi-Source Multi-Destination Networks

In this paper, a penalty-based distributed algorithm is proposed to design beamforming for Multi-Source Multi-Destination (MSMD) networks. The objective of the beamforming design is to minimize the transmission power of each source under the constraint that the Signal-to-Interference-plus-Noise Ratio (SINR) requirements of all source-destination pairs are satisfied. The proposed beamforming design has better power-efficiency compared to the egoism, altruism, and balancing algorithms. The convergence of the proposed algorithm is also discussed and a sufficient condition is determined for the algorithm to converge to a Pareto optimal solution.
