| Abstract: | The goal of blind beamforming is to recover source signals only from the output of array without any a priori information about the array manifold.For blind separation of the independent sources,Cardoso and Souloumiac proposed an effectively blind beamforming method(JADE) using fourth-order cumulant.However,the high computation complexity of this method limits its applicability in practical problems.In many applications,the source signals have nonzero third-order cumulant duo to the fact that they obey asym... |
