Device and method for transmitting filter bank multi-carrier symbols in wireless communication system

An apparatus for a transmitting end in a wireless communication system, the apparatus comprising:

• a transceiver;
• at least one processor operatively coupled with the transceiver, wherein the at least one processor is configured to control to:
• generate a first symbol in which sample values of a front end are shifted to a rear end, and generate a second symbol in which sample values of a rear end are shifted to a front end;
• and
• transmit a plurality of symbols comprising the first symbol and the second symbol on a time axis in an overlapping manner.

An apparatus for a receiving end in a wireless communication system, the apparatus comprising:

• a transceiver;
• and
• at least one processor operatively coupled with the transceiver,
• wherein the at least one processor is configured to control to:
• receive a signal in which a plurality of symbols overlap one another on a time axis;
• detect a first symbol in which sample values of a front end are shifted to a rear end from among the plurality of symbols;
• and
• detect a second symbol in which sample values of a rear end are shifted to a front end from among the plurality of symbols.
