The algorithm of TTCM-signaldecoding in channels with ISI

The soft decoding procedure of signal-sequence with turbo-trellis-coded modulation in channels with intersymbol interference is considered. The peculiarity of the decoder is the use of trellis-decision-feed-back with rib-metrics-computing, estimation signal-amplitudes, as well as a priory knowledge about the interchange on signal-amplitudes between MAP-decoders.
