Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an adjustment device for allocating power and a frequency of a terminal device in such a manner that mutual interference is suppressed.SOLUTION: An allocation device 151 includes calculation means 1511 and allocation means 1512. The calculation means 1511 calculates mutual interference cE/Efor which a ratio of energy Eper modulation symbol on a channel in GFDM with respect to energy Eper modulation symbol on a channel in OFDM is multiplied by a correlation coefficient (c), and calculates an inverse of a signal-to-noise power ratio in the case where a radio communication is performed by OFDM. The allocation means 1512 allocates power and a frequency to be used by a terminal device which performs a radio communication by GFDM, in such a manner that the mutual interference cE/Ebecomes sufficiently smaller than the inverse of the signal-to-noise power ratio.SELECTED DRAWING: Figure 9
【課題】相互干渉を抑えるように端末装置の電力および周波数を割り当てる調整装置を提供する。【解決手段】割当そうち151は、演算手段1511と割当手段1512とを含む。演算手段1511は、OFDMにおけるチャネルにおける変調シンボル当たりのエネルギーESOに対する、GFDMにおけるチャネルにおける変調シンボル当たりのエネルギーESGの比に相関係数cを乗算した相互干渉cESG/ESOを演算するとともに、OFDMによって無線通信を行うときの信号対雑音電力比の逆数を演算する。割当手段1512は、相互干渉cESG/ESOが信号対雑音電力比の逆数よりも十分に小さくなるようにGFDMによって無線通信を行う端末装置が使用する電力および周波数を割り当てる。【選択図】図9 |
