Abstract

A general framework of adaptive coordinated beamforming is proposed to enhance the performance of distributed antenna arrays network based on generalized sidelobe canceller (GSC). The proposed method exploits GSC structure to realize the convex combination of distributed neighboring nodes' weights sophistically such that the steady-state and robustness of antenna arrays network are greatly improved in strong interference environment. The optimal design as well as adaptive implementation by least-mean squares (LMS) algorithm is developed with detailed theoretical analysis on the stability and the steady-state output signal to interference plus noise ratio. Moreover, the effectiveness of the proposed method is demonstrated by simulation studies.
