Arbitrary Shaped Beamforming Codebook Design for Millimeter-Wave Communications

摘要

To transmit same data flow to users distributed in different directions simultaneously, this paper proposes a multi-beam codebook design scheme for multicast scenario based on phased array. By setting up and solving optimization model, weight vector can be found to generate beam that approximating the target beam with expected shape. Numerical examples are displayed, showing that the scheme is of great flexibility, both in methods to assign target beam, and different shapes that can be applied in different scenarios.
