Abstract | In this paper, a p-norm-like constraint normalized least mean square (PNL-CNLMS) algorithm is proposed for sparse adaptive beamforming. The proposed PNL-CNLMS algorithm inherits the good capacity of the conventional constrained least mean square (CLMS) algorithm in adaptive beamforming, i.e., forming ideal beam patterns. Also, the proposed PNL-CNLMS algorithm utilizes a p-norm-like constraint to exploit sparse property of the corresponding antenna array. In the derivation procedure, the Lagrange multiplier approach and the gradient descent method are utilized to obtain the devised updating equation. Numerical simulations reveal the superiority of the proposed PNL-CNLMS algorithm. |
