Area-based Primary Protection with Antenna Rotation Prediction for Dynamic Spectrum Access

DOI

説明

In this paper we propose a new primary protection for dynamic spectrum access, in which a secondary system uses a frequency band assigned to a primary system. Following an investigation in Japan, we consider a scenario where location information of a primary system’s reception (Rx) station facing its antenna boresight towards a moving transmission station is ambiguous. The proposed method performs the antenna rotation prediction and aggregate interference calculation at each protection point defined within an area where the Rx station may be installed. This area-based primary protection brings more operational opportunities to the secondary system under the scenario. We conducted computer simulations to demonstrate the effectiveness of the proposed method in practical urban scenarios and radio propagation models. The simulation results show that the proposed method can increase the number of available secondary base stations by about 24.4 times compared to a conventional method.
