Abstract

The present invention provides a method for resisting DC interference in orthogonal frequency division multiplexing (OFDM) system and the device thereof, which is to obtain the interference level of an OFDM system by a DC source corresponding to different modulation type and the frequency offset of the system from a simulation, and create a weighting look-up table, so as to give different weighting values for the interfered sub-carrier during decoding based on the weighting look-up table, compensate for the interfered unreliable signal with the reliable signal, and achieve the purpose of resisting DC interference in OFDM system.
