Abstract

The invention provides a secondary synchronization signal sequence processing method and a device thereof. The method includes the steps of utilizing secondary synchronization signal sequence index value determined according to physical cell group index, determining an output location of a shift register according to the secondary synchronization signal sequence index value and/or cell index after the shift register is initialized by using m-sequence, clockwisely shifting the shift register after the value of the output location is output, circularly performing the steps of outputting the value of the output location and clockwisely shifting the shift register, and finally obtaining the sequence. The secondary synchronization signal sequence processing method and a device thereof are capable of solving the problems of large consumption of resources, long processing time, high costs and low implementation efficiency in processing secondary synchronization sequence in the prior art, thereby having the effects of saving energy and improving processing efficiency.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing a secondary synchronization signal sequence. Background technique [0002] In the LTE system, the cell search process mainly includes the completion of time and frequency synchronization, the acquisition of the cell identification number, the determination of frame timing, and the detection of other control information of the cell. The cell search mainly uses the information of the Synchronization Channel (SCH for short) and the Broadcast Channel (BCH for short). Since the search is carried out step by step, in the process of cell synchronization and cell identification number acquisition, according to Due to different physical or logical functions, the SCH is divided into a primary synchronization channel (Primary Synchronization Channel, P-SCH for short) and a secondary synchronization channel (Secondary Synchronization Channel, S-SCH for sho...
