Abstract

The embodiment of the invention discloses a method and device for detecting main synchronous signals, and relates to the technical field of wireless communication. A lot of multiplying unit resources can be prevented from being consumed, and resources occupied by correlation calculation are saved. The method includes the steps that a local main synchronous sequence is obtained, normalized and rounded to obtain a normalized local sequence; a data receiving sequence is obtained, and correlation calculation and data processing are performed by using the normalized local sequence and the data receiving sequence to obtain a correlation result; according to the correlation result, the maximum peak position corresponding to the correlation result in a preset statistics duration is obtained, and target sector identification is determined according to the sector identification corresponding to the maximum peak position and the local main synchronous sequence. The method and the device are suitable for scenes for detecting the main synchronous signals.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for detecting a master synchronization signal. Background technique [0002] With the rapid development and wide application of communication technology, more and more users choose to use wireless user equipment to identify the network through cell search, and realize time-frequency synchronization to complete communication. At the present stage, it is necessary to obtain the sector identifier corresponding to the primary synchronization signal through the local primary synchronization sequence, and then obtain the secondary synchronization sequence according to the sector identifier, so as to realize cell search. In the prior art, the master synchronization signal detection system performs correlation calculation on the local master synchronization sequence and the received data sequence, and obtains the correlation peak value, judges w...
