Signal Processing in the Synchronization System of Communication Channel with OFDM

This paper is devoted to the study of the signal synchronization conditions in the 5G downlink. A model of the physical layer of a downlink communication channel is considered. The structure of the OFDM signal frame is investigated, the noise immunity data transmission is determined, and the error vector magnitude is estimated. A technique for ensuring signal synchronization while minimizing the error in a channel with OFDM signals is considered. Mechanisms have been developed for solving the problem ensuring the orthogonality subcarriers of OFDM signals in the condition’s interference.
