Abstract
This letter proposes a new iterative ISI equalization algorithm that offers low computational complexity: order L-2 with channel memory length L. The proposed algorithm is an extension of Reynolds and Wang's SC/MMSE (Soft Can celer 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 degrad ations from the trellis-based iterative equalization algorithms.
