The present application relates to a method for reducing the peak-to-mean amplitude ratio of a transmission signal comprising a plurality of coherent replicated signals, and to a transmitted for transmitting such a signal. The transmission signal is separated into the plurality of coherent replicated signals and one of the plurality of replicated signals is delayed with respect to another of the plurality of replicated signals, either in the time domain by introducing a time delay or in the frequency domain by introducing a phase shift. This has the effect of reducing the coherence of the delayed replicated signal with respect to the other replicated signal, reducing the peak power of the signal and therefore reducing the peak-to-mean amplitude ratio of the transmission signal. |
