| Abstract(in English) | The wireless communications including FWA are rapidly progressed. Therefore, the scarcity of frequencies continues to worsen. This paper discusses the capability of multi-channel common-band wireless communication systems with squared Butterworth spectrums, for the purpose of effective use of the frequency spectrum. If FWA at 25 GHZ on a 1 km hop has a canceling circuit that reduces the interference signal to 30 dB, it is shown that transmitted power of 2 mW can get received C/I of 39 dB under the rain attenuation of 18 dB. This means that the two-way multi-channel communications with the same frequency bands and the same polarization are realizable. Also, it is shown that inter-channel interference due to adjacent channels is negligible small in the case of channel separation of about 1.5 times the clock frequency. |
