Abstract
A method and/or system for stabilizing the operation of fractionally spaced equalizers has a number of taps (P), associated with which are respective equalization coefficients (c.sub.-L, . . . , c.sub.L), used in digital signal receivers, wherein the equalization coefficients (c.sub.-L, . . . , c.sub.L) are updatable to an algorithm (1) based on the minimization of a proper cost function (J) and stabilized for operation through a proper a modification (I) involving calculation of a plurality of values (I.sub.i) to be considered in updating the equalization coefficients (c.sub.-L, . . . , c.sub.L). According to the invention, these values (I.sub.i) are calculated in only one circuit (COMP) and serially transmitted to the fractionally spaced equalizer (FSE).
