Abstract
The invention relates to a method for estimating frequency bias negatively affecting a digital signal representative of a symbol frame, wherein said method comprises the steps of: generating the digital signal at a sampling period Te that is shorter than a predefined period of each of the symbols of the frame; 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; 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 for implementing the estimation method, as well as to a telecommunication method and system.
