Abstract
A time shifted replica signal (SLS) is generated from a reference signal (SPS) including a series of samples (A to K) describing bits of a data message, the sampling rate being at least twice the data message bit rate. The phases of the reference signal samples are determined with respect to virtual epochs (41) of the data message bits of the reference signal (SPS). The time shifted replica signal (SLS) is composed from the reference signal samples as a function of the phases of the reference signal samples. In another embodiment, the time shifted replica signal (SLS) is composed from the reference signal samples (A to K), the sampling rate of the replica signal (SLS) being the same as that of the reference signal (SPS), at least one reference signal sample (A to K) not being present in the time shifted replica signal (SLS).
