FIELD: information technologies.
SUBSTANCE: during conversion of symbols related to broadcasting signal, into tones, those symbols that are to be transformed into protective tones are nulled in process of transformation. In process of inversion, only central part of received signal is transformed without transformation of previously estimated number of protective tones.
EFFECT: reduced processor time spent for direct and reverse transformation of broadcasting signal symbols into tones.
