Abstract

In this letter, we propose a power control mechanism in order to improve secrecy rate defined as the difference between capacity of main link and wiretap link in a wireless multi-cell multiuser network. Through simulations, we verify that the proposed power control mechanism with threshold based user scheduling can significantly increase secrecy rate in a multi-cell environment.

본 논문에서는 무선 다중셀 다중 사용자 네트워크에서 전송용량과 도청용량의 차로 정의되는 기밀용량을 증대시키기 위한 단말의 전력조절 기법을 제안한다. 모의실험 결과를 통해 제안 전력조절 기법과 임계값 기반의 스케줄링의 결합이 다중셀 환경에서 기밀 전송률을 상당히 향상시킬 수 있다는 것을 확인하였다.
