摘要

In this paper, the L1-norm Linearly Constrained LMS (L1-LC-LMS) algorithm has been proposed. The L1-LC-LMS algorithm imposes the L1-norm restriction on the weights vector. By applying the L1-norm constraint, the weights vector convergence rate has been significantly improved. Furthermore, compared to traditional LC-LMS algorithm, the nulling depth of the L1-LC-LMS is greatly enhanced. The simulation is carried out in the arrays system with noise and other interferences. We have confirmed the effectiveness of the L1-LC-LMS algorithm from theoretical analysis and the experimental results.
