| Abstract(in English) | A spectrum sharing using cognitive radio technology has been attracted attention as a radical solution to a spectrum shortage. In the spectrum sharing, an unlicensed user (secondary user: SU) has to communicate under the protection of a licensed user (primary user: PU) by limiting the interference to the PU. In this paper, we propose a novel channel assignment method targeting high spatial efficiency while keeping minimum required signal power to interference power plus noise power ratio (SINR) of each SU under existing multiple SUs and channels. In the proposed method, a central control server is prepared and it assigns the channels to shorten the distance among SUs under considering aggregated interference to be kept less than the allowable interference at cell boundaries of SUs. We confirm that it is possible that the proposed method performs the channel assignment with high spatial efficiency while keeping every SU communication quality through computer simulations. |
