FIELD: radio engineering, communication.SUBSTANCE: invention relates to communication equipment and can be used in wireless communication systems at multiple access with orthogonal frequency division of channels (OFDMA). A processor receives a discrete signal containing transfer as to primary synchronisation signal (PSS) and transfer as to secondary synchronisation signal (SSS). The processor determines "P" correlations of the first symbol transmitted via PSS signal of the discrete signal with the first known symbol at each point of time "t" from time increments k of the discrete signal and "S" correlation of the second symbol transmitted via SSS signal with the second known symbol at each point of time t - 0.5/7 ms. The processor receives a version of phase slue ?out of the sum of "I" versions and determines "Cmax" correlations for all time increments k, with that, Cmax represents maximum amplitude of total correlation S and P at P turning through angle ?. The processor determines a cell identifier as per the first and the second known symbols giving S and P correlations leading to Cmax correlation and assessment of frequency shift between the discrete signal transmitter and the discrete signal receiver.EFFECT: improvement of quality of transmitting signals.16 cl, 9 dwg |
