The transmitter includes a unit (23) for generating a CDMA encoded information signal. A unit (21) generates a synchronisation signal, coding being performed using a synchronisation code that is not a CDMA communication code. The signal level is telemetrically adjustable. The synchronisation signal is transmitted in the same transmission channel as the information signal. A receiver includes a unit (15) for receiving and detecting a CDMA encoded information signal and a unit (11,12) for receiving and detecting a synchronisation signal. The unit (11,12) includes a logical correlator (11) and an accumulator (12). Independent claims are included for the receiver and for a synchronisation method. |
