Claim:
1. A method for generating a built symbol comprising a plurality of sub-symbols for transmission comprising data of an original symbol of an orthogonal multi-carrier modulation signal in order to reduce the peak-to-average power ratio (PAPR) of the orthogonal multi-carrier modulation signal, the original symbol lasting for a duration Ts and being carried by N orthogonal tones; the method comprising, by applying the intrinsic temporal-diversity properties of the complex N-points Inverse Fast Fourier Transform to the original symbol, generating the plurality of sub-symbols from the original symbol, wherein: the number of the generated plurality of sub-symbols is M, each of the M generated sub-symbols lasts for a duration Ts/M and is carried by N/M orthogonal tones, the M generated sub-symbols are time-multiplexed.
