Abstract (in Japanese) (See Japanese page) 
(in English) Scarcity of wireless channels leads the researchers to develop opportunistic spectrum usage systems. Spectrum sensing is the most important and complex job for the cognitive radios. Spectrum sensing may play a vital role to detect the presence of unknown emitters in a noisy and multi-path environment. In emergency situations (i.e. after earthquake) a number of rescue teams come to the field and setup their own radio communication systems. If the teams have no collaboration among themselves (which is most likely), they may interfere with each other by using same RF channels. One of the possible way to detect the presence of emitters is spectrum sensing. To utilize the advantages of Software Defined Radio (SDR) GNU Radio and USRP are used to capture the signal samples and store to a data file. Matlab communications toolbox is used to analyze the data and examine the spectrum. A number of theoretical analyses are available in literatures to detect the presence of signal. To investigate some of them from experimental perspective, we developed a spectrum sensing system with GNU Radio and USRP. GNU Radio based spectrum analyzers can be a cost effective solution for blind channel estimations also.
