Abstract: The present disclosure provides a method for performing beamforming. The method includes initiating a first signal transmitted from a target second device to be received by a first device having an antenna array. A first beamforming weight matrix is generated by the first device that automatically corrects amplitude and phase errors of the antenna array and maximizes antenna gain toward the target second device using a covariance matrix derived from the received first signal. An enhanced second beamforming weight matrix is then generated by the first device using a mask window or a jointly optimized algorithm to further suppress interference to and from other active second devices. The enhancement is computed and applied based on the distribution of multiple active second devices. The antenna array is steered using the second beamforming weight matrix to transmit to and receive from the target second device with an optimized antenna beam pattern.
