Abstract: The present invention relates to a transceiving method and apparatus that enable QAM signal transmission in a filter bank multi-carrier (FBMC) communication system and provides, in particular, a transceiving method and apparatus that enable quadrature amplitude modulation (QAM) signal transmission without intrinsic interference by separating filtering between a sub-carrier having an even index and a sub-carrier having an odd index, and superimposing and transmitting sub-carriers filtered by means of separation. The thus-rendered present invention is a transmission method in the FBMC communication system, the method comprising the steps of: dividing at least two QAM signals into a plurality of groups; performing filtering on each of the plurality of groups; and superimposing and transmitting the QAM signal in the plurality of groups filtered on a time axis. The present invention relates to a transmission method and apparatus, and a corresponding reception method and apparatus.
