| 摘要 |
The invention relates to a method of sending a multicarrier signal implementing an OQAM type modulation, intended to be transmitted via a transmission channel, formed of a temporal succession of symbols consisting of data elements modulating a carrier frequency of said signal, a carrier frequency modulated by one of said data elements being called a carrier, a set of carriers being allocated to a sender device. According to the invention, the method of sending comprises a step of inserting a sequence of pilots specific to said sender device at a given instant in the multicarrier signal on said allocated set of carriers, said sequence of pilots comprising: - a sequence of non zero complex values, inserted on the odd or even carriers, alternating with zero values, inserted on the other carriers respectively even or odd, - the non zero complex values of the sequence of pilots, their frequency transforms and inverse frequency transforms having constant envelope, and - a sequence of zero values modulating the carriers of the allocated set of carriers at the next instant. |
