This paper describes a novel technique for promoting sparsity in the modified filtered-x algorithms required for activ e noise control. The proposed algorithms are based on recent techniques incorporating approximations to the l0-norm in the cost functions that are used to derive adaptive filtering algorithms. In particular, zero-attracting and reweighte d z roattracting filtered-x adaptive algorithms are developed an d considered for active noise control problems. The results of si mulations… CONTINUE READING
