“…In Figure 12 shows the dependence of the bit error rate (BER) [7] on SNR (𝐸 𝑏 /𝑁 0 ) for the PSS and the PBCH. The frequency offset versus SNR for 5G mobile telecommunications is shown in Figure 13.…”

“…In the literature [5], [6], a description of numerology, signals and the procedure for achieving synchronization is given, but the dependence of the inter-correlation functions of the primary synchronization signal (PSS) at low signal-to-noise ratios (SNR) and on skip of synchronization is not investigated. In [7], [8] there is also no estimate of the shifts in the time and frequency domains that occur at low SNR and at the synchronization skip. Youssif et al [9] it is shown that if the sampling rates on the transmitting and receiving sides of the OFDM channel are out of phase, a symbol synchronization error occurs, which can generally be attributed to clock synchronization errors.…”

The article investigates the operations of identifying a cellular network and searching for a cell at various signal-to-noise ratios. The estimation of frequency and time displacement, criteria for detecting the primary synchronization signal are presented. The main contribution of this article is the consideration of the step-by-step execution of the 5G cell search procedure in a complex interference environment. The decoding steps of the primary and secondary synchronization signals are being investigated. This is achieved by analyzing the signals at each step of the correlation algorithm for different signal-to-noise ratios. In order to verify the adequacy of the proposed models, a sequence operation for synchronizing 5G mobile networks with base station signals is considered. The dependence the magnitude of the error vector modulus on the signal-to-noise ratio of a physical broadcasting channel is investigated for three different channel profiles without line of sight. As a result of the experiment, the error vector of the physical broadcast channel changes from 55% to 10%, when the signal-to-noise ratio changes from 0 to 20 dB. In the multiple-input multipleoutput (MIMO) mode, we received a 3 dB increase in communication energy efficiency. The findings will be useful for 5G system designers to troubleshoot synchronization problems.

The article explores megatrends in management, related to the transition to digital technologies in all spheres of the economy and production in the COVID-19 pandemic. The main contribution to the analysis of the current state of digitalization HR in business. The possibilities of a set of processes and methods of interaction with information in the formation of a strategy of people's management, are investigated. This is achieved through the use of integrated mobile applications and the automation of HR processes. From the results, the methodology for determining the severity of competences, indicators of behavior are proposed, the strengths and weaknesses of the company's staff management system in the COVID-19 conditions are taken into account. The practical usability of work is due to the proposed competency-based approach, which makes it possible to increase the efficiency of personnel selection, taking into account key macro-competencies that find an applied form through appropriate behavioral indicators.
