PCT No. PCT/FR94/00670 Sec. 371 Date Feb. 6, 1996 Sec. 102(e) Date Feb. 6, 1996 PCT Filed Jun. 7, 1994 PCT Pub. No. WO94/29971 PCT Pub. Date Dec. 22, 1994A signalling packet for a communication system has a reference signal to support time and frequency synchronization. The reference signal is modulated so that it varies with time according to a predetermined modulation law. The variation is with respect to both the I and Q channels. Because of the variation with time, receivers can synchronize in frequency and in time with a base station in a simplified manner. Doppler shift can be determined and compensated.
