Title:
METHOD AND DEVICE FOR CLOCK SYNCHRONIZATION
Document Type and Number:
WIPO Patent Application WO/2018/112903
Kind Code:
A1
Abstract:
Disclosed in the present application is a clock synchronization method, relating to the field of communication technologies. The method comprises: acquiring a first sequence, the first sequence being a part of a to-be-received sequence of a receiver, the first sequence having the same length as a training sequence cyclically sent by a transmitter; performing channel estimation of the first sequence, to obtain a first impact response of a main channel, the main channel being a channel through which the to-be-received sequence of the receiver passes; delaying the first impact response of the main channel to a different degree, to obtain a first delay value, the first delay value being a delay value corresponding to the first impact response having the highest energy concentration; and correcting a clock phase, according to the first delay value. The method for clock synchronization disclosed in the present application can realize clock synchronization in the case where the channel condition is poor and a high-order modulation signal is used.
