The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention discloses a transmitting and receiving method capable of estimating an accurate time and a frequency synchronization using a sequence in a filter bank multiple transmission system. The present invention comprises: mapping sequences corresponding to filters, respectively; adopting an auxiliary sequence which helps a sequence for a synchronization to maintain a correlation attribute; drawing the auxiliary sequence which facilitates a time and frequency synchronization estimation and does not influence a data demodulation. According to the present invention, a time and frequency synchronization may be accurately estimated through a synchronization sequence and an auxiliary sequence which are generated by a filter bank multiple transmission method.
