摘要：Apparatus and method for recognizing Global System for Mobile

communication (GSM) signals are provided. The solution comprises obtaining position andtiming information from a satellite positioning system; tuning to a frequency channel with

GSM transmission; collecting a group of I/Q samples for the length of 12 GSM frames;performing peak detection using at least two peak detectors over the group of sampleswherein the found peak values are the locations of synchronization bursts (SCH). For thefound peaks, the timing information, carrier-to-noise ratio, in phase and quadraturevalues are determined. A group of I/Q samples for the length of 12 or 51 GSM frames arecollected. From the found SCH, base station identification code BSIC, frame number andBroadcast Control Channel (BCCH) training sequence are determined. BCCHscorresponding to all SCH are decoded; and transmitting base stations identified.
