| Abstract(in English) | Multiple frequency band transmission has been studied to realize broadband wireless communications in which plural frequency bands are simultaneously used. This paper studies a generation method of out-of-band noise reduction signals using a part of used signal bands to reduce out-of-band noise power which is harmful interference in existing systems in multi-band OFDM transmission. The effect of distortion noise reduction with the method is evaluated by computer simulations. The results of computer simulations show that the method can improve the Signal-to-Noise Ratio (SNR) of an out-of-band user by 1.8 dB in which the receiving power ratio of the user is －20 dB to a multi-band user. |
