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 FDMA signal communications by satellites.

摘要： A device (D) is dedicated to data stream processing within a communication satellite of a communication network. This device (D) comprises processing means (MT) whose job is, in the event of receipt of a first incoming data stream whose carrier exhibits a first modulation and comprising at chosen locations chosen insertion blocks, i) to detect the insertion blocks and at least one characteristic of the carrier of the first incoming stream, chosen from among its frequency, its phase, its timing and its amplitude, ii) to modulate, in accordance with the first modulation and having regard to each detected characteristic, data packets to be transmitted to a destination common with that of the first incoming stream, and iii) to replace with the modulated packets certain at least of the insertion blocks detected in the first incoming stream which has not been demodulated, so that the resulting stream is transmitted by the satellite, with its first original modulation, to the common destination so as to be demodulated therein as if it had been constituted by a single modulator.
