Abstract

A fast algorithm to generate the Blocking Matrix for Generalized Sidelobe Canceller (GSC) beamforming is proposed in this paper. The proposed algorithm uses a simplified zero placement algorithm (SZPA) to directly generate the independent null space vectors by specifying the zeros of the corresponding Z domain polynomials following the constrained signal incoming angle. Compared to the conventional methods based on Singular Value Decomposition (SVD), this method can be more than 10 times faster for scenarios with 15 constraints and will be even more advantageous for more constraints with the same converged state performance. Numerical simulation confirms the efficiency and effectiveness of the algorithm.
