The influence-analyz of decision-feed-back by signal-processing in channels with inter-symbol interference on limited analyze-interval

In this paper view two demodulators of signal-sequence in channels with intersymbol interference: demodulator on base the maximum-likelihood principle, this foresee full sorting all signal-sequences on limited time-interval; and length-limited equalizer. The probability-performance findings of imitation-modeling and distance-performance findings by direct-calculation are presented. Show, that the decision-feed-back improve the noise-defense of system in spite of errors-reproduction effect.
