METHOD OF MULTIPLE INITIAL SEARCHES FOR CDMA AND GSM SYSTEMS Russian patent published in 2008 - IPC H04B1/707 

Abstract RU 2328820 C2

FIELD: methods for performance of simultaneous searches.

SUBSTANCE: in mode IS-95 hardware of search device performs time multiplexing in row of search device time intervals, every of which may generate "ПШ" sequence for compression of data sequence. In GSM mode hardware of search device is configured as row of different GSM channels, every of which may generate unique sequence of gold code for tracking of GSM signal from specific GSM satellite. This configuration gives the possibility to search device to perform multiple searches of GSM signals simultaneously. Search hardware may be dynamically configured with the possibility of operation either in IS-95 mode, or in GSM mode, excluding necessity in specialized circuits for every mode of operation.

EFFECT: increase of search conduction rate.
