FIELD: communication networks.
SUBSTANCE: method is used, when frequencies spectrum B splits due to busy narrowband channels on separate partial frequencies sub-ranges. Method allows to directly use given frequencies range and excluded busy frequencies without additional costs of hardware. frequencies range B is divided on N sub-channels SCn, while bearings of sub-channels SC2, which have busy frequencies EFR1, are not modulated. In particular method can be used for communication via high-voltage distribution networks.
EFFECT: decreased frequencies band for transfer channel with non-homogeneous frequency range.
