Primary Protection with Antenna Rotation Prediction for Dynamic Spectrum Access

View Publication

Abstract

In this paper we propose a new primary protection method 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 a primary system’s transmission (Tx) station moves along a predefined course or area, and a reception (Rx) station keeps facing its antenna boresight towards the moving Tx station. The proposed method takes the movement of the Tx station into account and predicts a range of the variation of the Rx station’s antenna boresight for accurate interference calculation. The accurate interference calculation 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 11.0 times compared to a conventional method.
