Abstract: A method of generating a time shifted replica signal (SLS) from a reference signal (SPS) comprising a series of samples (A to K) describing bits of a data message in which the sampling rate is at least twice the data message bit rate is disclosed. The method comprising the steps of determining the phases of the reference signal samples with respect to virtual epochs (41) of the data message bits of the reference signal (SPS); and composing the time shifted replica signal (SLS) from the reference signal samples as a function of the phases of the reference signal samples. Also disclosed is method comprising the step of composing the time shifted replica signal (SLS) from the reference signal samples (A to K), wherein the sampling rate of the replica signal (SLS) is the same as that of the reference signal (SPS), and wherein at least one reference signal sample (A to K) is not present in the time shifted replica signal (SLS).
