Abstract
A method for the estimation of the transfer function of a transmission channel in a receiving system of UMTS type envisages the computation of a plurality of channel coefficients, included among known channel coefficients corresponding to pilot symbols, through the reiteration of an interpolation algorithm, capable of calculating an intermediate point (Z, f(Z)) between a first extreme and a second extreme of a determined interval, the first extreme being formed by at least two known points and the second extreme being formed by at least one known point, the intermediate point to be calculated having as abscissa (Z) the abscissa value of the mean point between the points defining the interval rounded off to the integer closest to the first extreme, and having as ordinate (F(Z)) the arithmetic average between the ordinate of the known point of the second extreme and the ordinate of a point, chosen between the two known points of the first extreme, having a distance from the intermediate point equal to the distance between the intermediate point and the known point of the second extreme.
