초록

최근 들어 다양한 이동 수단의 발전과 함께 철도 또한 많은 발전을 이루었다. 이렇게 발전된 철도 시스템과 더불어 정확한 철도 시스템 정보 전달을 위한 효율적인 통신시스템이 요구되었고, 이에 따라 철도 통신 시스템 또한 다양한 방식으로 발전했다. 철도 무선통신에서 페이딩의 영향을 최소화 하고 보다 효율적인 통신을 하기 위해, 협력 통신방식이 제기되었다. 본 논문에서는 다양한 방식의 무선 통신방법 중 협력 전송 기법에 대해 소개하고, 이에 따른 채널 특성과 통신 예시 등을 소개할 것이다.

In recent years, according to improvement of various vehicle instruments, railway also has been developed in various fields. As a result, to transmit accurate information to each railway system, the efficient communication system is required. In railway communication system, mitigation of wireless fading is very important. So, in this paper we introduced the cooperative relay channel model and cooperative relay scheme. Also we analyzed and simulated the cooperative relay scheme which is suitable for railway communication systems.
