    The invention related to a communication system with good transmission characteristic with a simple circuit by determining the parameter of a function by means of setting an input/output value as the variable of the function, finding the extremum of the output characteristic function by the determined parameter and detecting the extremum as the peak of a correlation value. A circuit estimating an approximate function and finding the extremum generates a signal Wi+1 obtained by delaying one timing of a differential signal Wi by a delay element, fetches the codes of the differential signal Wi and Wi+1 by code decision circuits and calculates the product in exclusive OR. The circuit briefness, detecting the extremum as the peak of a correlation value.
