Abstract

In this study, a method for an electromagnetic spectrum umbrella (ESU) is proposed. In the three-dimensional space covered by the ESU, the unlicensed user cannot normally receive the desired electromagnetic wave signal and the authorized user can receive the desired electromagnetic wave signal. The construction method of the ESU is discussed herein. The optimal three-dimensional layout of interference devices is presented. The receiver sensitivity loss of the unlicensed user receiver is analyzed. The structure of the authorized user receiver and its receiver sensitivity loss bound are presented. Finally, simulation and experimental results are provided for demonstrating the effectiveness of the proposed method.
