Abstract(in Japanese) (See Japanese page)
Abstract(in English) We have proposed the framework of white space boundary estimation with a smaller number of sensing points. The framework decides the white space boundary by estimating coverage of incumbent radio systems with positions of transmission sources and predicted pathloss. To consider the local propagation characteristics around the transmission sources for estimating the coverage, we are studying the method of azimuth variable pathloss fitting. The variables are decided by weighted least squares method, of which weighs are based on the angle difference between the azimuth of pathloss fitting and every sensing point. In this paper, we describe experimental evaluation about predicted pathloss and white space estimation with our studied method.
