Abstract;The wireless communications including FWA are rapidly progressed. Therefore, the scarcity of frequencies continues to worsen. This paper proposes a new system, the common-band wireless communication system, for the purpose of effective use of the frequency spectrum. It provides two-way communications with the same frequency bands and the same polarization, using a canceling circuit that cancels the transmitted signal which cause interference to a received signal. In the case of FWA at 25GHz on a 1km hop, if a canceling circuit reduces the interference signal to 30dB, carrier-to-interference ratio will be about 38dB. This means that the common-band wireless communication system is realizable. (author abst.)
