Abstract: Provided are a method and apparatus for estimating and correcting the phase error in 5G or pre-5G communication systems providing much higher data rates compared to existing 4G communication systems including LTE systems. The existing phase error estimation scheme using a cyclic prefix in the time domain may fail to prevent performance degradation due to inter-carrier interference. In the present invention, it is possible to enhance reception performance of the receiver by estimating and correcting the phase error multiple times within a symbol using a time domain signal and by reducing the influence of inter-carrier interference.
