Abstract (in Japanese) (See Japanese page) 
(in English) In IEEE802.11ac and LTE-Advanced which are expected for next generation radio communication systems, bonding frequency channels and expanding the channel spacing are discussed in order to enhance the data rate.
In contrast to this, on frequency sharing systems, co-channel interferences will be increased due to expanded channel spacing.
Therefore, the channel capacity is not always enhanced by expanding the channel spacing.
In this paper, theoretical study of the optimal channel spacing under common channel interferences is reported.
Moreover, independently changes of the channel spacing is often repeated when there are multiple distributed communication links which use common frequency channels.
This interaction between multiple links is discussed by applying game theory.
