FIELD: physics; communication.
SUBSTANCE: invention concerns data transfer, in particular, to signal and synchronisation reception. For this purpose the first pilot signal is applied together with three stages of capturing. At the first stage attempt of supervision of a front edge of the curve correlation connected with a symbol of the first pilot signal is made. At the second stage determination, whether a front edge at the first stage has been found out, by means of attempt of supervision of flat band and-or a back edge of curve correlation, is made. Besides, the autofrequency trim system can be updated for the account of frequency shift throughout this second stage. The third stage is intended for supervision of back edge of a curve if it was not observed any more at the second stage. After detection and acknowledgement of reception of the first pilot signal, the second pilot-signal can be applied to reception of fine reading of the symbol time subsequently.
EFFECT: increase of synchronisation accuracy.
