Abstract: A method and an apparatus for transmitting/receiving a signal by using a variable band width in a communication system are disclosed. An operating method of a terminal comprises the steps of: receiving, from a base station, first configuration information about one or more guard bands of an unlicensed band; confirming the one or more guard bands configured in the unlicensed band on the basis of the first configuration information; and confirming a plurality of RB sets configured in the unlicensed band on the basis of the one or more guard bands. Therefore, performance of the communication system can be improved.

Abstract: Disclosed are a method for acquiring synchronization in a cable network, and a physical (PHY) transmitter and PHY receiver. The method for acquiring synchronization in a cable network according to an embodiment includes receiving, by a PHY receiver, a signal from a PHY transmitter, and acquiring, by the PHY receiver, channel synchronization when a symbol in which a channel preamble exists is detected from the received signal and a position of a frequency in which a channel subcarrier exists is detected from the detected symbol by performing a cross correlation operation on the received signal and the channel preamble.

Abstract: A Faster-Than-Nyquist (FTN) signal transmission apparatus and method thereof. The signal transmission apparatus includes a pilot interference estimator and compensator configured to estimate interference on pilot symbols by a Faster-Than-Nyquist (FTN) signal generated by FTN modulating a sequence of data symbols, and generate a compensated pilot symbol sequence to cancel the estimated interference; a pilot FTN modulator configured to generate an FTN pilot signal in which inter-pilot symbol interference does not occur, by performing FTN pulse-shaping on the compensated pilot symbol sequence; and a transmitter configured to transmit an FTN data signal and the FTN pilot signal.
