ABSTRACT: A method of and an arrangement for determining the optimum position of the reference tap of a master adaptive equalizer which adapts itself to variations of the channel of a digital system for transmitting data (which are in general complex) by modifying its sets of coefficients used to determine the transmitted symbols. Simultaneously with the operation of the master adaptive equalizer and for consecutive analysing periods: - a selection is made, in a slave adaptive equalizer, of the position of the reference tap and a subsequent adaptation of its coefficients in accordance with a se- lection algorithm and an adaptation algorithm, respec- tively; - a comparison is made between the symbols supplied by the master and slave adaptive equalizers in accordance with an error criterion; and - in the case in which the error criterion indicates that the slave adaptive equalizer provides the best results, said position and said coefficients are transferred from the slave adaptive equalizer to the master adaptive equalizer.
