Provided is transmitting and receiving apparatus and a channel compensation method in a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM) in a wireless communication system. The receiving apparatus in the wireless communication system according to an embodiment of the present invention includes first and second estimators, an interference canceller, and a determination unit. The first estimator estimates an interference quantity detecting an interference in a received signal, the second estimator estimates a Signal-to-Noise Ratio (SNR) with the exception of a noise quantity corresponding to the estimated interference quantity. The interference canceller cancels the interference from the receiving signal. And a determination unit controls the operation of the interference canceller based on at least one of the estimated interference quantity and the estimated SNR.
