차세대 이동통신 시스템의 전송 기술 후보로 시간 영역 확산 MC-CDMA 시스템이 주목을 받기 시작했다. 이러한 시스템에서는 데이터와 파일럿 기호가 시간 영역에서 확산되고 코드 다중화됩니다. 페이딩 문제를 해결하려면 코드 다중화된 파일럿 기호를 사용하여 채널 추정을 수행해야 합니다. 특히 차세대 시스템에서는 최대 도플러 주파수를 높이는 현재 시스템보다 높은 주파수 대역을 사용할 것으로 예상돼 보다 강력한 채널 추정 방법이 기대된다. 이를 고려하여, 우리는 매우 정확한 채널 추정을 위한 채널 추정 방법을 제안합니다. 이는 2차원 채널 추정 방법과 임펄스 응답 기반 채널 추정 방법을 결합한 것입니다. 우리는 컴퓨터 시뮬레이션을 통해 제안된 방법을 평가합니다.

Abstract: As a candidate for the transmission technology of next generation mobile communication systems, time-domain spreading MC-CDMA systems have begun to attract much attention. In these systems, data and pilot symbols are spread in the time domain and code-multiplexed. To combat fading issues, we need to conduct channel estimation by using the code-multiplexed pilot symbols. Especially in next generation systems, frequency bands higher than those of current systems, which raise the maximum Doppler frequency, are expected to be used, so that a more powerful channel estimation method is expected. Considering this, we propose a channel estimation method for highly accurate channel estimation; it is a combination of a two-dimensional channel estimation method and an impulse response-based channel estimation method. We evaluate the proposed method by computer simulations.
