Abstract

In this paper, we propose a pilot symbol assisted low complexity LS channel estimation method for OFDM in fast time varying channels. The proposed method shows low complexity characteristics in terms of memory space and processing time compared with conventional BEM channel model LS estimation methods.

본 논문에서는 고속 시변 채널 OFDM을 위한 파일럿 심볼을 이용하는 저복잡도 LS(Least Square) 채널 예측 방식을 제안한다. 제안된 방식은 기존의 BEM(Basis Expansion Model) 채널 모델 LS 예측 방식과 비교하여 동일한 성능에서 저장공간 및 계산량이 줄어드는 저복잡도 특성을 나타낸다.
