A class of block-iterative equalizers for intersymbol interference channels fixed channel results.

A new and efficient class of nonlinear equalizers is developed for intersymbol interference (ISI) channels. These -"iterated-decision equalizers? use an optimized multipass algorithm to successively cancel ISI from a block of received data and generate symbol decisions whose reliability increas...
