摘要：The invention relates to a multicarrier transmission method including symbols(33) consisting of a set of subcarriers, including pilot subcarriers (36) dedicated to at leastone processing for assisting and/or improving decoding in at least one receiver, and datasubcarriers (35), the location in time-frequency space and a reference value of said pilotsubcarriers being known to the receiver. Said method includes a phase of modifying, for agiven symbol (33), the reference value of at least one subset of said pilot subcarriers, by aphase and/or amplitude correction datum for each of said pilot subcarriers of saidsubset, in order to minimise the peak-to-average power ratio, said correction data havingat least three separate values, the transition between the values of two consecutive pilotsubcarriers of said subset being constant on the frequency axis.
