A study of antenna beam direction estimation for dynamic spectrum sharing

Abstract

To realize dynamic spectrum sharing, it is necessary to avoid interference from the secondary system to the primary system. Technical information such as the position of the radio station and the antenna specification of the primary system are required to estimate interference to the primary system accurately, but these specifications are not generally disclosed. In this paper, we propose a method for estimating the antenna beam direction using only information on the received power at the radio wave sensors. Using the simulation data and the outdoor measurement data, the evaluation confirmed the effectiveness of the proposed method.
