FIELD: physics; communications.
SUBSTANCE: invention relates to a transmission system with an extended spectrum, specifically with spectrum spreading through a direct sequence, which is used in code division multiple access systems (CDMA) and can be used in satellite navigation systems. For this purpose a code phase signaling unit generates a code phase signal to assist in receiving a spread-spectrum signal, received by a receiver module from a transmitting module. The code phase signal is used by the receiver module to synchronise the synchronisation code phase, which is formed in the receiver module, with the phase of the modulating code of the said spread-spectrum signal, received by the receiver module, where the synchronisation code sequence corresponds to the modulating code sequence. The code phase signaling unit generates a signal which represents time shift of the synchronisation code from the reference time, which is related to transmission time of a defined reference part of the modulating code, and the time shift is related to transmission time of the subsequently transmitted shifted part of the modulating code.
EFFECT: cutting on synchronisation time.
