Abstract

In this paper, the constellation rearrangement method for retransmission based on Chase combining, is introduced. And the effectiveness of the recommended constellation rearrangements is analyzed with statistics. Their performance for turbo-coded or convolutional coded bit streams is evaluated with simulation under additive white Gaussian noise environment.

본 논문은 물리 계층에서의 HARQ방식에서 사용하는 체이스 결합 기반의 재전송 방법에서 재전송시 신호 성상점 재배치방법에 따른 성능 분석 결과를 제시한다. 성능 분석은 16QAM 변조방식에 국한하여 가산형 백색 가우스 잡음 (AWGN) 환경에서 모의실험을 통해 이루어진다. 터보 부호와 길쌈 부호의 두 가지 채널 부호화 방법에 따른 성능 분석 결과를 제시한다.
