Abstract

In this paper, we propose an Adaptive Modulation and Coding (AMC) scheme using relay protocols generally known as Relay Node (RN). The AMC scheme is used for improving the throughput and a reliability of a communication system, because of the nature of different modulation and coding schemes. We analyze the performance of relay protocols with the AMC scheme and observed that relay protocols with the AMC scheme is capable of providing better average throughput at a lower Signal to Noise Ratio (SNR) level as compared to the conventional scheme with no AMC. We perform Monte Carlo simulations with Long Term Evolution-Advanced (LTE-A) parameters to prove the performance comparison of adaptive Modulation and Coding Scheme (MCS) relay protocols with the non-adaptive MCS relay protocols. The simulation results of the proposed system with adaptive MCS prove that among the Amplify-and-Forward (AF), Decode-and-Forward (DF) and DeModulate-and-Forward (DMF), the DMF protocol performs best at a lower SNR value and also provides better average throughput.

본 논문에서는 AMC(Adaptive Modulation and Coding) 기법을 적용한 릴레이 프로토콜을 제안한다. AMC 기법은 다양한 변조와 코딩 기법을 통해, 통신 시스템의 전송률과 신뢰도를 향상시킬 수 있다. 본 논문에서는 AMC 기법을 적용한 릴레이 프로토콜의 성능을 분석하고, AMC 기법이 적용된 릴레이 프로토콜이 AMC 기법이 적용되지 않은 기존의 기법과 비교하여 낮은 SNR(Signal to Noise Ratio) 레벨에서 더 좋은 평균 전송률을 제공할 수 있음을 확인하였다. 비적응적 MCS(Modulation and Coding Scheme) 릴레이 프로토콜과 적응적 MCS 릴레이 프로토콜의 성능을 증명하기 위해 LTE-A(Long Term Evolution-Advanced) 파라미터와 함께 몬테카를로 시뮬레이션을 수행하였다. 모의실험 결과, 적응적 MCS가 적용된 시스템에서 AF(Amplify-and-Forward), DF(Decode-and-Forward) 및 DMF(DeModulate-and-Forward) 프로토콜 중 DMF 프로토콜이 낮은 SNR 값에서 가장 좋은 성능을 보이고, 더 좋은 평균 전송률을 제공하는 것을 확인하였다.
