FIELD: communication facilities.
SUBSTANCE: there are detected high power signals. Defined frequency range can be frequency range "decurrent circuit. "Frequency range " ascending circuit ", which must be used, can be defined from known ratio of frequencies between defined carrying " decurrent circuit " and corresponding carrying " ascending circuit " or by means of monitoring of defined frequency range of " decurrent circuit " for information, indicating frequency range carrying " ascending circuit ", which must be used. There are described methods of search of carrying, including search of narrow-bands of high power, used, in order to provide information about carrying and/or to indicate frequency range, which must be tracked.
EFFECT: definition of high power signals with removal of necessity of timing of symbols and evaluation of channel for definition of signals, used for definition of frequency range, which must be used.
