Abstract

Relay-assisted multi-input multi-output (MIMO) technique has become a promising candidate for next generation broadband wireless communications for high speed access. In this paper, we propose channel selective relay-based MIMO transmission system. The performance of relay-based system can be improved by using the subcarriers selectively based on the channel condition between relay and mobile station. Simulation results show that the proposed relay-based system considerably outperforms the conventional relay-based system.

초고속 접속을 위한 차세대 광대역 무선 이동 통신 기술의 하나로서, 중계기를 활용한 다중 입출력 기술이 유력하게 연구되고 있다. 본 논문에서는 채널 선택적 중계기 기반의 다중 입출력 전송 시스템을 제안한다. 중계기와 단말기 사이의 채널 상태에 따라 선택적으로 부채널을 사용함으로써 수신 성능을 크게 향상시킬 수 있다. 실험 결과를 통해, 제안된 중계기 기반 시스템의 성능이 기존의 시스템 성능보다 우수한 특성을 나타냄을 확인하였다.
