<p>The method involves generating, for a gateway (CX1), a pilot signal (Fp) on a service carrier frequency, and transmitting the pilot signal to a gateway (CX2). The pilot signal is used for assuring a phase and time synchronization of the signals from the two gateways in order to carry out a transmit diversity. A part of a transmission band of one of the signals is assigned to the pilot signal. Independent claims are also included for the following: (1) a system for transmitting wanted signals via a satellite using gateways (2) a gateway comprising a transmitter to transmit a wanted signal in a defined transmission band.</p> |
