METHOD AND MODULE FOR ESTIMATING FREQUENCY BIAS IN A DIGITAL-TELECOMMUNICATIONS SYSTEM

摘要

The invention relates to a method (30) for estimating frequency bias negatively affecting a digital signal representative of a symbol frame, wherein said method (30) comprises the steps of: (300) generating the digital signal at a sampling period Te that is shorter than a predefined period of each of the symbols of the frame; (302) calculating values for a plurality of pairs of samples of the digital signal, each value being representative of a phase difference between the samples of a pair; (304) estimating the frequency bias negatively affecting the digital signal on the basis of the values calculated for Np pairs of samples selected such that a plurality of said Np pairs belong strictly to a single symbol in the frame. The present invention also relates to a module (217) for implementing the estimation method (30), as well as to a telecommunication method (40) and system (1).
