We use the correlation amplitude to decide which 7.68 MHz wide snapshot encompasses the LTE signal center frequency. Once the signal in one snapshot is classified as LTE, two more snapshots are captured in order to cover 20 MHz, the maximum LTE bandwidth.

The center frequency of an LTE carrier is assumed to be on a 100 kHz channel raster (known also as carrier grid) in order to allow the LTE UEs to search a limited number of carrier frequencies in the frequency bands they support and synchronize within a reasonable amount of time after being activated.18 May 2018
