The present application relates to a method, device and system for frequency point synchronization. Wherein, the above method includes the steps: when the working frequency point of the repeater equipment is out of sync, based on the synchronization frequency point, the synchronization of the working frequency point is carried out; the synchronization frequency point is obtained by searching within the frequency point search range; the frequency point search range It is the frequency band determined according to the central frequency point of the working frequency band of the repeater equipment. By automatically matching the center frequency point to flexibly adjust the frequency point search range, and realize the intelligent frequency point synchronization of the TDD system. The carrier synchronization method provided by this application is more flexible, and can automatically detect changes in the center frequency point of the working bandwidth, quickly adjust the search range of the synchronization frequency point, and at the same time improve the accuracy of searching for the synchronization frequency point. When using TDD signals, it can automatically, quickly and accurately search for synchronization frequency points, and use the searched synchronization frequency points to achieve fast synchronization.
Description
technical field [0001] The present application relates to the field of communication technologies, and in particular to a method, device and system for frequency point synchronization. Background technique [0002] At present, in the repeater equipment, the carrier frequency point search and the working frequency point synchronization of the TDD (Time Division Duplexing, Time Division Duplex) system signal need FPGA (Field-Programmable Gate Array, Field Programmable Gate Array) to pass the input The frequency control word corresponding to the carrier frequency NCO (numerically controlled oscillator, digitally controlled oscillator) is used to judge whether the input carrier frequency is synchronized. However, during the implementation process, the inventors found at least the following problems in the traditional technology: when frequency points are synchronized, the flexibility and accuracy of searching for actual synchronization frequency points are poor.
