FIELD: data transfer.
SUBSTANCE: correction term is used in method and unit for equaliser with decision feedback to compensate limiter errors and avoid errors distribution. Filter factors for equaliser are selected so as to minimise cost functions for equaliser including correction term as filter factor energy function. Equaliser contains factor generator which is sensible to correction term. Optionally, transmitted symbol from received selection is assessed as signal/inference-noise ratio (SINR) of received selection. Received selection is quantised and displayed in field of network superimposed on the transmitted set of symbols. This field may correspond to the assessed value of symbol or extra processed to get assessed value of symbol.
EFFECT: minimisation of cost function for equaliser.
