METHOD AND SYSTEM FOR EFFICIENT bandwidth for transmitting / receiving communication signal USING BANDWIDTH CHANNEL

摘要

FIELD: information technologies.;SUBSTANCE: invention discloses a method to transfer an additional signal along a channel having a transfer band, comprising multiple used subbands occupied with transfer signals. According to this method, availability of free subbands not occupied with transfer signals is detected, and the additional signal is sent through usage of free subbands. According to this method, the additional signal is multiplexed by usage of a CDMA code and is transferred in OFDM subcarriers having frequencies in free subbands.;EFFECT: efficient transfer, reception of communication signal transfer capacity control by use of a channel pass band.;4 cl, 6 dwg
