METHOD FOR DYNAMICALLY EVALUATING PILOT-SIGNAL FILTER BAND WIDTH

摘要

FIELD: method and device for dynamic adjustment of pilot-signal filter parameters.;SUBSTANCE: in accordance to the invention, input signal, containing pilot-signal, is subjected to filtration with usage of non-identical filters, and values of filtered signals are compared for estimating width of pilot-signal band width. Also noise, contained in input signal, may be evaluated, preferably in the part of input signal, which, as expected, does not contain a pilot signal. Based on comparison of values of filtered signals, noise investment in which may be compensated, parameters of filter, used for filtration of input signal to select pilot-signal, are changed. These parameters may change band width of pilot signal filter.;EFFECT: improved selection of pilot-signals in presence of noise.;8 cl, 7 dwg
