ABSTRACT:
A method for adjusting a phase difference between a received code modulated signal and a replica code sequence where, in order to enlarge the control range, it comprises a step of determining measurement values representing a phase difference between a received code modulated signal and a generated replica code sequence. The proposed method further comprises determining coefficients for a loop filter operation, which coefficients optimize a predetermined function specified for current properties of the received signal. Then, a loop filter operation is applied to the measurement values to obtain an indication of a required correction of a current frequency of the generated replica code sequence, which loop filter operation utilizes the determined coefficients. Finally, the frequency of the generated replica code sequence is adjusted based on the indication of a required correction. The invention relates equally to a corresponding unit and to a corresponding system.
