In order to recover the statistically imdependent source signals，the paper proposes a novel blind beam-forming approach based on two-order statistics．In this method，the source signals are extracted by the statistic properties of the zero cross-correlation between any two source signlas，under the case of unknown array manifold．The approach can be applied to the array beamforming with arbitrary array manifold and error．The method requires that the noise is white and the source signals are colored or deternuninistic，and not requires the estimation of arrival-direction of signals．In extracting source signals，it will make SNR be largest．On thecontrary to the blind beamforming besed on higher-order statistics，it is simple and robust，and can extensively be applied to the blind separation of mobile communication signals．
