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.
Read moreWhat is LTE raster?
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
Read moreWhat is DL frequency?
In case of FDD (Frequency Division Duplex) LTE downlink channel (DL, eNB transmits UEs receive) and uplink channel (UL, UEs transmit eNB receives) are transmitted simultaneously on different frequencies. Also each band is marked by LTE release number where it was defined.
Read moreWhat is DL Earfcn in LTE?
EARFCN stands for E-UTRA Absolute Radio Frequency Channel Number .In LTE, the carrier frequency in the uplink and downlink is designated by EARFCN, which ranges between 0-65535. EARFCN uniquely identify the LTE band and carrier frequency.
