Outline of Final Research Achievements

In this research project, spectrum usage measurement techniques has been investigated to achieve an accurate and efficient (low computational cost) spectrum usage measurements. Especially, we focus on cooperative spectrum usage measurement system in which multiple sensors cooperate with each other. At first, we develop signal processing techniques for the spectrum measurement in a sensor, after that a cooperation process by the multiple sensors has been investigated. A validity and efficiency of the developed techniques were confirmed by the spectrum measurement demonstrations.
