摘要： 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.

摘要： A satellite for a satellite telecommunication system transmits signals at different powers on the downlink connection. The powers are chosen to limit the relative dynamic range of signals received on the downlink connection. The relative dynamic range of signals received on the downlink connection is advantageously less than 5 dB and preferably less than 2 dB. A digital processor circuit is used, together with an analog-digital converter, a circuit taking the fast Fourier transform of the converted signals, a circuit for monitoring the gain of the signals, a circuit for switching the signals to at least two amplifier subsystems each including an inverse fast Fourier transform circuit, a digital-analog converter and a power amplifier.
