Abstract

In this paper, we introduce the amplify-and-forward (AF) cooperative diversity with multiple relays using phase feedback. Simulation results show that the AF cooperative diversity with multiple relays using phase feedback not only provide the better performance than the direct transmission, but also obtain the diversity gain according to the number of the cooperating terminals. The performance of proposed scheme using tolerable feedback is close to optimal performance.

본 논문에서는 위상 피드백을 사용하는 다중 사용자를 위한 증폭재전송 협동 다이버시티 기법을 소개한다. 시뮬레이션 결과는 위상 피드백을 사용하는 다중 사용자를 위한 증폭재전송 협동 다이버시티 기법이 기존 무선 통신 기법에 비해 향상된 성능을 제공할 뿐 아니라 협동에 참여하는 단말기 수에 따라 다이버시티 이득을 얻음을 보여준다. 제안된 기법은 적은 양의 피드백만으로도 완전한 피드백을 사용한 경우에 근접하는 성능을 제공한다.
