Abstract

A robust approach to implement the multidimensional fast least squares (FLS) algorithm for linearly-constrained adaptive spatial/temporal filtering is presented in this work. It can be directly applied in adaptive beamforming for broadband signals. Simulation results illustrate the performance of the proposed approach which is compared with the classical LMS based Frost algorithm
