    Abstract: 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). A system and method for constructing an interference component using a detected data symbol and an estimated channel response in a non-orthogonal system and a method of estimating a channel using a structure of the non-orthogonal system and the interference component is disclosed. The system includes a receiver that receives a reference signal and data transmitted from a transmitter; detects adjacent data symbols around the reference signal; estimating an initial channel state; constructs the interference signal on the basis of the adjacent data symbols and the initial channel state; estimates the channel state on the basis of the constructed interference signal; and performing an iterative process of reconstructing the interference signal on the basis of the estimated channel state and re-estimates the channel state on the basis of the reconstructed interference signal.

    Abstract: A method and apparatus for transmitting symbols for use in an FBMC wireless communication system are provided. The FBMC symbol transmission method includes determining a truncation point of a first FBMC symbol overlapping a transient transmission duration based on an energy distribution characteristic of a first filter applied to the first FBMC symbol, wherein the first FMBC symbol is to be transmitted in a non-transient transmission duration, truncating the first FBMC symbol at the truncation point in the transient transmission duration, changing an energy characteristic of a second filter, filtering the first FBMC symbol using the second filter, filtering FBMC symbols positioned within the non-transient transmission duration based on a non-transient transmission duration characteristic; and transmitting the filtered FBMC symbols at a corresponding transmission timing.
