Holographic Distributed Coherent Beamforming

In this paper, we present a novel application of distributed coherent communications labelled holographic beam-forming, in which a distributed, cooperative relay implements a distributed transmit beamforming solution to improve the throughput and resilience of communications systems in a multi-user environment. We derive an MMSE beamforming solution to the posed problem. In a MATLAB simulation platform, we characterize the performance improvement of the proposed solution in terms of sum-rate, and compare this performance against a traditional frequency-division, multiple-access strategy leveraging single-user distributed coherent beamforming. With these results, we demonstrate a substantial throughput increase under certain configurations and discuss the limitations of the proposed approach in others.
