Robust adaptive beamforming based on a new steering vector estimation algorithm
Autor: Wei-min Jia, Wei Jin, Shuhua Zhou, Min-li Yao
Publikováno v: Signal Processing. 93:2539-2542
A new approach to the design of robust adaptive beamforming is introduced. In the proposed approach, the mismatch vector of the desired steering vector is estimated by solving a quadratically constrained quadratic programming problem using an interfe
