Abstract: A method of transmitting a multi-carrier source signal, including symbols constituted by reserved carriers and data carriers. The method includes generating an additional signal that reduces peak-to-average power ratio of the signal to be transmitted. For each symbol, the method obtains M time samples representing the symbols and/or at least one iteration of: detecting P time samples from among P time samples representing the symbol, the P samples being the P samples of the highest amplitude among the M samples, or the P samples presenting a power value above a threshold; in the frequency domain, activating a reserved carrier, by addition of a pre-determined power to the reserved carrier; and for each activated reserved carrier: obtaining M time samples representing the activated reserved carrier, and applying a phase shift, taking account of the P detected samples, to the M time samples representing the activated reserved carrier.
