Abstract
A method for transmitting a multi-carrier signal implementing an OQAM-type modulation, formed of a temporal succession of symbols including data elements modulating a carrier frequency of the signal. A carrier frequency modulated by one of the data elements is called a carrier, wherein a set of carriers is allocated to a transmitter unit. The method includes inserting a sequence of pilots specific to the transmitter unit at a given time into the multi-carrier signal on the allocated set of carriers. The sequence of pilots includes: a sequence of non-zero complex values, inserted on odd or even carriers, alternating with zero values, inserted on the other carriers, respectively even or odd-numbered; non-zero complex values of the sequence of pilots, their frequency transforms and inverse frequency transforms being with a constant envelope; and and a sequence of zero values modulating the carriers of the set of carriers allocated at the following time.
