Résumé: This letter proposes a new iterative ISI equalization algorithm that offers low computational complexity: order L<superscript>2 with channel memory length L. The proposed algorithm is an extension of Reynolds and Wang's SC/MMSE (Soft Canceler followed by MMSE filter) equalizer: approximations are used properly to reduce the computational complexity. It is shown that the approximations used in the proposed algorithm do not cause any serious performance degradations from the trellis-based iterative equalization algorithms.
