Embodiment Construction

[0052] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0053] Such as figure 1 As shown, in the wireless transmission environment-oriented IEEE1588 protocol optimization system of the present invention, at both ends of the wireless channel, the master clock node 1 modulates the baseband signal with pilot information to the transmitting antenna module 3 through the channel modulation and demodulation module 2 and radiate energy. Before receiving the signal from the receiving end of the clock node 8 to the signal processing module 7 through the receiving antenna module 4, it needs to go through the processing link of the power adjustment module 5 and the synchronous processing module 6 to obtain the maximum processing amplitude gain. After ideal synchronization processing, the receiving...

Description

technical field [0001] The invention relates to a time synchronization technology in the communication field, in particular to an IEEE1588 protocol optimization system and method for wireless transmission environment. Background technique [0002] With the development of network communication technology, the role of clock synchronization in distributed systems is becoming more and more important. At present, in order to realize the synchronization of high-precision distributed clocks, a well-known and relatively effective method is to realize clock synchronization in the Ethernet network through the IEEE1588 synchronization protocol. The full name of IEEE1588 is "Precise Clock Synchronization Protocol Standard for Network Measurement and Control Systems". It uses both software and hardware and software to achieve more accurate timing synchronization. This protocol can be used in all networks that support multicast function, such as Ethernet. Ethernet has the advantages of ...
