摘要
This correspondence presents a new approach to adaptive beamforming (adaptive reconstruction of a desired signal in the presence of interferers and noise) using just a single snapshot to calculate the antenna weights. As in previous work in this field, a structured and grouped array of sensor elements is assumed. The concept exploits the induced special data structure, which can be described as a generalized rank-one eigenvalue problem and can be solved by means of a linear (overdetermined) system solver. Arbitrary signal statistics are allowed and no difficulties with nonstationary and coherent interferers arise. Furthermore, there does not exist any transient behavior of the algorithm. Simulations verify its very good performance in comparison with the optimum beamformer.
