초록

이동통신 시스템에 적용되는 적응변조방식의 변환은 주변 환경을 고려한 변환을 사용하므로, 변환 조건 및 이에 따른 전송량의 변화에 대한 관점에서 다루었으나, 이동통신 단말기와 같이 에너지 효율이 좋아야 하는 경우에는 이러한 적응방식이 성능을 낮게 할 경우가 발생한다. 따라서 전송효율만을 고려하던 기존방식에서 소비 에너지를 고려하고, 프레임 길이를 조절하여 사용하는 적응변조방식을 제어하는 최적화 방식을 제안한다.

In this paper, the optimum transmission method is proposed to save the energy and to increase the throughput of the adaptive modulation mobile radio system with frame length control. Traditionally, adaptive modulation has been used to improve the throughput using the power margin of the system design. Considering the frame length vs energy saving and adaptive modulation, the optimum transmission method is proposed for hub and mobile station each.
