Abstract(in English) Currently, in various wireless LAN systems, there is a possibility of narrow-band interferences from other communication systems. As a method to reduce these interferences, this study uses DCM (Dual Carrier Modulation) that distributes and transmits information to separated subcarriers of OFDM signals. By performing demodulation of DCM using only information of subcarriers not affected by interferences, degradation due to narrow-band interferences can be reduced. Further, weighting processing is performed on the demodulated signal of DCM according to the influence of interference. It was confirmed that the improvement of BER characteristics can be obtained by the proposed scheme against narrow-band-interferences.
