| Abstract(in English) | With the recent development of wireless communication technology, depletion of frequency resources is regarded as a problem. As a solution, frequency sharing has attracted attention. One of the problems of frequency sharing is interference with a primary user by a secondary user. For secondary spatial frequency use, it is essential to estimate the interference so as not to interfere with other systems. It is necessary to monitor the interference model due to changes in the radio wave environment and movement of temporary users. In this paper, we investigate the interference estimation method using radio wave sensors linked with the spectrum database. With respect to the interference model estimated by the database, the interference fluctuation is detected from the actual signal power distribution detected by the radio wave sensor using a test. Computer simulations revealed the sensitivity of detecting fluctuations in the interference model using radio wave sensors. |
