Equalizer with decision feedback with high modulation rate

This paper analyses-data of decision feedback equalizer in multi-path channels by higher relative modulation-rate is presented. At this analyses results receipt on the basis of equivalent discrete-time channel-model with intersymbol interference (ISI), which uses the adaptive filter, which matched with pulse-response of channel. The distance-characters and index of ISI-remainder analyse for equalizer, which provide the minimum of ISI-remainder by constants sample's value of demodulate sequence-element. This paper also demonstratives, that satisfactory demodulation by equalization with feedback ensured in the channels with multi-path spreading and higher relative modulation-rate.
