| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we consider cognitive radio technology, which has gained attention around the world. We focus on the coexistence environment between cognitive radio and fixed radio systems and consider two scenarios. First scenario is that cognitive radio system only has the function of detecting signals of other wireless systems in order to avoid the interference to fixed radio systems. Second one is that cognitive radio system has an additional function, which can avoid an unavailable arbitrary frequency band because of existence of the busy wireless system. Then, hidden terminal problem is considered in these scenarios . We indicate that the cognitive radio which equips the function of detecting and avoiding other wireless systems cannot communicate without interference when hidden terminals exist, while cognitive radio with additional function can communicate with almost no interference even with hidden terminals. |
