Abstract

The present invention provides a demodulation method, device, terminal, and system, wherein the demodulation method includes: acquiring communication information of a cell, performing blind solution to a synchronization signal in the communication information, and obtaining a blind solution result, The time range information carried in the communication information is determined according to the blind solution result, and the communication information is demodulated according to the time range information. The solution of the present invention can determine some conditions of the communication information of the cell by means of the obtained prior information, thereby reducing assumptions when demodulating the communication information, reducing demodulation complexity, and reducing power consumption.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a demodulation method, device, terminal and system. Background technique [0002] A mobile communication system refers to a system in which operators provide communication services for user terminals (such as mobile phones) by deploying radio access network equipment (such as base stations) and core network equipment (such as Home Location Register, HLR). Among them, the mobile communication system has experienced the first generation, the second generation, the third generation and the fourth generation. The first-generation mobile communication system refers to the initial analog cellular phone standard, which is limited to voice calls, mainly using analog technology and Frequency Division Multiple Access (FDMA) access method; the second-generation mobile communication The system introduces digital technology, improves network capacity, improves voice qu...
