8-PSK turbo equalization with the list-sequential (LISS) algorithm

We consider coded 8-PSK transmissions over intersymbol interference channels with a long impulse response and employ a receiver performing iterative equalization and decoding. This paper also uses the techniques from sequential decoding adapted to the equalization task in a turbo scheme. This list-sequential (LISS) equalizer operates on a tree and approximates the a posteriori probabilities with reduced complexity.
