| 摘要 | 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 8th order 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 8th order 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. | ||

| 主权项 | 1. An apparatus comprising at least one processor configured to cause the apparatus to: obtain as an input a sampled signal; determine a parameter for a group of samples of the input signal corresponding to the length of one or two frames of a Global System for Mobile communication (GSM) signal, the parameter describing the shape of the group of samples; determine peak to average power and peak to average power variance for the group of samples of the input signal corresponding to a length of one or two frames of a GSM signal; compare the determined parameter to predetermined thresholds and the obtained peak to average power and peak to average power variance to predetermined thresholds; and determine whether the input signal is a GSM-type signal on the basis of the comparisons. | ||
