FIELD: radio transmission systems. SUBSTANCE: the device has an access buffer for storage of signals received by antenna of the base station in the form of accesses, device for determination of time delay so as to obtain the value for determination of time delay so as to obtain the value of correlation between the signal in the specific observation position determined by the access buffer and the reference signal, which corresponds to the specific symbol during determination of the specific symbol and specific observation position by means of the signal processor, signal processor intended for determination whether there is a signal component in the specific observation position with dew account made for the common mean correlated value received from the device for determination of time delay, and a multibeam adder for determining the symbol to be indicated to the time delay device. EFFECT: reduced probability of erroneous decision during determination whether there is some signal, delayed by the channel at multibeam propagation of signal, in a specific observation position of the time delay axis. 2 cl, 2 dwg
