Embodiment Construction

[0045] The "plurality" mentioned herein means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The symbol " / " generally indicates that the contextual objects are an "or" relationship.

[0046] Before introducing the present application, the technical names involved in the present application are first introduced.

[0047] A clock signal, used as the basis for sequential logic. For example, taking the central processing unit (English: center processing unit, referred to as: CPU) as an example, the clock signal is used as its reference, and all signal processing inside the CPU must use the clock signal as a scale, so that the execution of CPU instructions can be determined through the clock signal. speed. Wherein, the clock signal may be a square wave signal, the period of ...

Abstract

Embodiments of the present application provide a clock synchronization method and device, which relate to the field of communication technology, and solve the problem that user data information is interrupted when clock synchronization is implemented in an existing CDMA system. The method is applied in a code division multiple access system, including: the transmitting end drives the first sequence code by sending a clock to obtain a signal carrying a clock, and the signal carrying a clock is a square wave signal; wherein, the first sequence code Including N symbols; the time length between any two jump edges of the square wave signal is an integer multiple of the time length for sending the first sequence code, and each symbol in the N symbols The time lengths are equal; the N is an integer greater than or equal to 1, and when the N≥2, the N symbols are the same; the transmitting end sends a transmitting signal to the receiving end; wherein the transmitting signal includes The clock-carrying signal; the clock-carrying signal is used to implement clock synchronization between the receiving end and the transmitting end.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a clock synchronization method and device. Background technique [0002] Code division multiple access (English: code division multiple access, referred to as: CDMA) is a carrier modulation and multiple access connection technology based on spread spectrum communication. The signals used for data information transmitted by different user terminals are not based on frequency or time. Gap is different to distinguish, but with their own different coding sequences to distinguish. Among them, CDMA is mainly used in wireless communication, and there is a problem of low signal-to-noise ratio (English: signal to noise ratio, abbreviation: SNR) when using CDMA system for data information communication. Therefore, the method of clock synchronization can be used to improve Performance of CDMA system. [0003] At present, in the CDMA system, a pseudo-random sequence (E...
