摘要
A method is provided for transmitting a multicarrier signal formed by a temporal succession of multicarrier symbols, which includes: at least one preamble formed by at least three successive multicarrier symbols, known as preamble symbols, including complex-value data elements each associated with a carrier of the signal; and multicarrier symbols, known as data symbols, including real-value data elements each associated with a carrier of the signal. The method includes a carrier-shaping step including filtering the carriers of the preamble symbols using a first prototype filter, and filtering the carriers of the data symbols using a second prototype filter different from the first prototype filter.
