Abstract

This paper proposes an optimal relay selection and adaptive throughput enhancement scheme utilizing superposition modulation in cooperative communication. The optimal relay is selected and the channel state is estimated by utilizing superposition modulation. The source determines the number of superimposed signal in accordance with the estated channel state. As a result, throughput is increased in accordance with the channel state.

본 논문은 협력 통신에서 중첩변조를 활용한 최적의 중계단 선정 및 적응적 전송률 향상 기법을 제안한다. 중첩변조를 활용한 중계단 선정 신호를 활용해 최적의 중계단을 선정함과 동시에 채널 상태를 추정하여 중첩되는 신호의 수를 결정하여 채널 상태에 따라 적응적으로 전송률을 향상시키는 기법을 제안한다.
