| Popis: | In this work, we consider a distributed reduced-rank beam coordination problem over array networks. We develop an inherently adaptive combination scheme based on combination matrix for beam coordination problem. Two adaptive efficient implementation strategies for diffusion reduced-rank beamforming are proposed. Illustrative simulations validate that the proposed distributed reduced-rank adaptive algorithms could remarkably improve the convergence speed in comparison with the existing techniques under the condition of small samples. |
