Abstract:
1. An apparatus comprising at least one processor configured to cause the apparatus to: control a receiver to tune to a frequency channel with Global System for Mobile communication (GSM) transmission; control a receiver to collect a first group of in phase and quadrature (I/Q) samples; perform correlation on the first group of I and Q samples; perform peak detection using at least two peak detectors over the group of samples wherein the found peak values are the locations of synchronization bursts (SCH); for the found peaks, determine the timing information, carrier-to-noise ratio, in phase and quadrature values; control a receiver to collect a second group of in phase and quadrature (I/Q) samples; and from the found SCH, determine identity information of the received transmission.
