Analysis of Signal Synchronization Conditions in 5G Mobile Information Technologies

The article is devoted to the study of the hardware description language (HDL) implementation the cell search procedure for the initial initialization of user equipment in a mobile communication system of 5G technology. The energy search criteria are analysed depending on the signal-to-noise ratio. The features of the implementation the principles formation of the cell identifier physical layer is considered. The concept of constructing a synchronization error detector is described. Experimental studies of the formation an estimate the offset of the frequency performing the correlation between the cyclic prefix of each orthogonal frequency division multiplexing (OFDM) symbol and the appropriate parts of the OFDM symbols are presented. Evaluated the coarse and accurate frequency offset in 5G mobile telecommunications.
