본 논문에서는 송신기 다이버시티를 갖는 OFDM(Orthogonal Frequency Division Multiplexing) 시스템을 위한 효율적인 채널 추정 기법을 제안한다. 제안된 기술은 "comb-type" 트레이닝 심볼을 사용하여 시공간 코딩 OFDM 시스템에 필요한 모든 채널 주파수 응답을 고유하게 추정합니다. 제안하는 기법은 모든 처리가 주파수 영역에서 이루어지기 때문에 기존 MMSE(Minimum Mean-Squared Error) 기법에 비해 계산 복잡도를 획기적으로 줄였다. 또한, 제안된 접근 방식의 성능을 더욱 향상시키기 위해 무작위 잡음 효과를 완화하고 채널 변화를 추적하는 몇 가지 다른 기술이 논의됩니다. 제안된 접근 방식의 성능은 모바일 무선 채널에 대한 컴퓨터 시뮬레이션을 통해 입증됩니다.

Abstract: In this paper, we propose an efficient channel estimation technique for orthogonal frequency-division multiplexing (OFDM) systems with transmitter diversity. The proposed technique estimates uniquely all channel frequency responses needed in space-time coded OFDM systems using "comb-type" training symbols. The computational complexity of the proposed technique is reduced dramatically, compared with the previous minimum mean-squared error (MMSE) technique, due to the processing made all in the frequency-domain. Also, several other techniques for mitigating random noise effect and tracking channel variation are discussed to further improve the performance of the proposed approach. The performances of the proposed approach are demonstrated by computer simulation for mobile wireless channels.
