In this paper, a correntropy induced metric (CIM) criterion based set-membership NLMS (SM-NLMS) algorithm is proposed and its derivation is given in detail for estimating a sparse channel identification system. In the proposed algorithm, the CIM is utilized to exploit the sparsity-aware property of the sparse broadband multiple-path channels to achieve a better channel state information (CSI). Moreover, the proposed CIM criterion based SM-NLMS (CIMSM-NLMS) algorithm is carried out by mimicking… CONTINUE READING
