Abstract (en)
[origin: WO2008088353A1] The present invention discloses a method and system for improving the robustness of interference nulling for antenna arrays in a wireless communication network. The method is comprised of generating a first interference spatial signature from an interference signal matrix received by the antenna array, deriving a second interference spatial signature from the first interference spatial signature, calculating a covariance matrix from the second interference spatial signature, and generating a beamf orming weighting vector from the covariance matrix.
