This paper addresses the problem of sparse channel estimation in orthogonal frequency-division multiplexing (OFD-M) systems. A novel sparse channel estimatior using iterative half thresholding algorithm based on L<sub>1/2</sub> regularization is proposed. Compared with the traditional greedy pursuit and L<sub>1</sub> regularization, the merit of the new(More)
