Abstract (in Japanese) (See Japanese page) 
(in English) This paper evaluates spectrum efficiency with the proposed method which adaptively control bandwidth and transmit power of a multi-band wireless system according to the used band and Signal-to-Noise Ratio (SNR) of an interfered system and an inter-system power ratio. The channel capacity of the multi-band system is calculated from bandwidth utilization rates and SNRs of the multi-band system by computer simulation, and spectrum efficiency improvement is evaluated. The evaluation results show that there is the region where the proposed method can improve the channel capacity of the multi-band system by adaptive control of transmit power and bandwidth according to the used band and SNRs of the interfered system.
