Abstract :
In this paper, a novel beamforming scheme is proposed for reception of coherent signals and suppression of strong interference. An interference-blocking (IB) transformation is first developed for removing the strong interference, while the desired signals and noise are retained. Optimum beamforming is then performed based on the IB transformation data consisting of only the desired signals and noise to produce maximum output signal-to-interference-plus-noise ratio (SINR). Numerical results demonstrate that the proposed interference-blocking maximum signal-to-noise ratio (IB-MSNR) beamformer significantly outperforms the conventional beamformers and can approximately achieve the performance of the optimum beamformer
