Abstract
This method for estimating a carrier-frequency offset in a telecommunication signals receiver comprises the following steps: computation of the partial correlations relating to several successive portions of a reference binary sequence, each partial correlation being computed between a portion of a signal received by the receiver at said carrier frequency, this signal comprising said reference binary sequence, and a predetermined portion of said reference binary sequence stored and/or generated by the receiver, in several possible relative positions between the received signal and the predetermined portion, and determination of the carrier-frequency offset from the computed partial correlations. It also comprises a step of selecting a synchronization position and the determination step comprises the estimation of a phase shift between computed partial correlations at the selected synchronization position.
