发明名称 CONSTRUCTION OF A MULTICARRIER SIGNAL
摘要 A multicarrier signal to be transmitted to digital receivers, particularly in a non-stationary transmission channel, corresponding to the frequency multiplexing of a plurality of elementary carriers each corresponding to a series of symbols is described, wherein two consecutive symbols are separated by a symbol time tau 0. The spacing nu 0 between two adjacent carriers in the signal is equal to half the reciprocal of the symbol time tau 0 and each carrier is subjected to spectrum formatting filtering with a bandwidth which must exceed twice the intercarrier spacing nu 0, and selected so that each symbol is highly concentrated in the time and frequency domain. Methods for transmitting and receiving such a signal are also described.
