Method of and arrangement for determining the optimum position of the reference tap of an adaptive equalizer

Abstract From the Canadian patent

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 selection algorithm and an adaptation algorithm respec-, tively;, - a comparison is made between the symbols …
