FIELD: information technologies.
SUBSTANCE: circuits are proposed to improve resources of multiplexing of control symbols sent from various mobile stations at the same frequencies and same time intervals, without noise and/or shift. In system of multiple access with orthogonal frequency division with jump-like tuning of frequency, control symbols between subscribers may be overlapped. Orthogonality between subscribers, control symbols of which overlap, is provided as a result of application of orthogonal sequences of control symbols and individual scrambling codes for specific sectors and for specific cells of cellular communication.
EFFECT: invention provides for reliability of transferred control symbols reception.
