Synchronization and Cell Search Procedure in 3GPP 5G NR Systems

In this paper, we design cell search and synchronization procedures involving the primary synchronization signal channel for the 3rd Generation Partnership Project (3GPP) 5th Generation (5G) New Radio (NR) Systems. More specifically, we present two approaches, one is based on auto-correlation and the other is based on cross-correlation. Moreover, to extract synchronization signals from large transmission band, an efficient filtering method is proposed. Numerical results are also provided to evaluate and compare the two different approaches.
