Trust Degree Based Beamforming for MISO Cooperative Communication System

摘要

For a multiple-input-single-output (MISO) cooperative communication system, we consider a beamforming design problem by taking into account trust degrees between nodes. For given trust degrees, we design the optimal transmit beamformer in terms of an expected achievable rate as a linear combination of channel vectors weighted by trust degrees. In the numerical results, it is shown that the achievable rate can be increased by exploiting the trust degrees between nodes on the beamforming design.
