A Study of Sensing Sensitivity Improvement Method Using Iterative Cooperative Sensing
Mai Ohta, Takeo Fujii (UEC) SR2010-71
Abstract (in Japanese) (See Japanese page) 
(in English) For cognitive radio, a cooperative sensing detects statistically vacant spectrum by collecting observed information from many sensing nodes. The cooperative sensing can decrease an influence of the fading, however some wireless resource is used to transmit the information. Gathering sensing information causes the interference to a primary system (PS) if we share the channel with PS. In general cooperative sensing, a large number of information improves the cooperative sensing ability. However we cannot get enough performance, because the sensing information exchange area becomes small for avoiding the interference to PS. In this paper, we study a method that the sensing information exchange area is expanded by iterating the cooperative sensing. Finally, we confirm the effectiveness of our proposed method by evaluating the relationship between the number of iteration and the area expansion.
