Abstract
Apparatus and method for recognizing Global System for Mobile communication (GSM) signals are provided. The solution comprises obtaining as an input a sampled signal; determining the 8order moment for a group of samples of the input signal corresponding to the length of one or two frames of a GSM signal; determining peak to average power and peak to average power variance for the group of samples of the input signal corresponding to the length of one or two frames of a GSM signal; comparing the obtained 8order moment to predetermined thresholds and the obtained peak to average power and peak to average power variance to predetermined thresholds; determining whether the input signal is a GSM-type signal on the basis of the comparisons.
