파일럿 심볼을 이용하여 전파왜곡을 정밀하게 보상하는 방법은 이동통신에서 널리 사용되고 있다. 우리는 플랫 페이딩과 주파수 오프셋의 정확한 보상을 위한 파일럿 기호 지원 기술을 설명합니다. 이 기술은 광범위한 오프셋 보상을 제공합니다. 고속 푸리에 변환(FFT)을 사용하는 기존 방법은 느린 페이딩과 빠른 페이딩을 모두 보상하지만 허용 가능한 주파수 오프셋 범위는 매우 제한적입니다. 근사 주파수 추정기로 시스템을 구성함으로써 페이딩과 큰 주파수 오프셋을 동시에 추정하고 보상할 수 있습니다. 추정 및 보상은 주기적인 파일럿 심볼에 의해 수행되며 다른 인덱스 시퀀스는 필요하지 않습니다. 이 방법을 사용하면 고속 데이터 전송이 가능합니다. 우리는 파일럿 심볼을 갖는 전송 프레임 구조에 대한 보상 가능한 페이딩 범위와 주파수 오프셋에 대한 방법을 설명하고 이론적 분석을 제공합니다. 그런 다음 컴퓨터 시뮬레이션을 통해 방법을 평가합니다.

vol. E85-A, no. 7, pp. 1656-1664, July 2002, doi: .
Abstract: Methods that precisely compensate for propagation distortion using pilot symbols are widely used in mobile communications. We describe such a pilot-symbol-assisted technique for precise compensation of flat fading and frequency offset. This technique provides a wide range of offset compensation. Conventional methods using fast Fourier transform (FFT) compensate for both slow and fast fading, but their tolerable range of frequency offset is very limited. By composing a system with an approximate frequency estimator, we can estimate and compensate for fading and a large frequency offset at the same time. The estimation and compensation are carried out by periodic pilot symbols and no other index sequences are needed. This method enables high-data-rate transmission. We describe the method and provide a theoretical analysis for the compensable range of fading and frequency offset for a transmission frame structure with pilot symbols. Then, we evaluate the method by computer simulation.
