Description

technical field

[0001] The present invention relates to a method and device for generating an auxiliary synchronization code in a Wide Code Division Multiple Access WCDMA (Wide Code Multiple Access) wireless communication system in the communication field, in particular to a method and a device for generating an auxiliary synchronization code in real time when a mobile terminal searches for a cell . Background technique

[0002] In wideband code division multiple access mobile communication system, because WCDMA system base stations do not require accurate synchronization, it mainly identifies cells through different scrambling codes, so cell search is one of the key technologies of WCDMA physical layer. When the mobile terminal starts up, it needs to get in touch with the system. First, it needs to get timing synchronization with the signal of a certain cell. This process from no contact to timing synchronization is the cell search process of the mobile station. Through the...
