On Codebook Design for Distributed Relay Beamforming Network

The authors study the problem of codebook design for quantized distributed relay beamforming under individual relay power constraint in a cooperative relay network. The received SNR is used as the design metric. They study two types of codebook design: phase-only codebook where each relay uses full power, and codebook with power control where relay power and phase need to be jointly considered. For the former, they adopt Grassmannian line packing criterion under equal gain constraint, and compare the performance with that under the generalized Lloyd Algorithm for optimal codebook design.
