Abstract
The invention relates to a method for transmitting signals termed useful signals via a satellite by means of connection stations. To this end, a first connection station (CNX1) carries out the generation of a first service signal on a service carrier frequency dubbed the pilot signal (Fp), and the transmission of this pilot signal to at least one second connection station (CNX2). The use of this pilot signal ensures phase synchronization and temporal synchronization of the signals so as to implement a transmit diversity, that is to say to toggle the transmission of the useful signal by this second connection station without loss of phase synchronization between the two stations. The invention applies to the Frequency Division Multiple Access (FDMA) signal communications by satellites.
