FIELD: information technology.
SUBSTANCE: invention refers to wireless networks and to the methods of extraction of sub-carrier data in OFDM system. Control unit (108) selects first sub-carrier data of high quality, thereby planning, based on receiving quality information (CQI), transmitted by a terminal, communication participant, and information of the required transfer rate for each terminal, communication participant. Control unit (108) selects second data, earlier denoted sub-carrier. The channel selection unit (115) selects sub-carrier channels indicated by the control unit (108).
EFFECT: increased efficiency of transmission due to selection of sub-carriers by planning in accordance with data type, allowing for achieving low energy consumption and high speed signal processing.
