摘要
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.
