본 연구에서는 WFrFT(Weighted Fourier Transform) 통신 시스템의 송신 신호의 시간-주파수 대칭성을 이용한 Blind Carrier Frequency Offset(CFO) 추정 방법을 제안한다. Blind CFO 추정은 WFrFT 매개변수를 특정 값으로 설정했을 때 푸리에 변환 전후의 신호 파형을 일치시키는 특성에 중점을 두어 이루어집니다. 제안된 방법이 기존의 추정 방법보다 레일리 페이딩에 더 강함을 수치 시뮬레이션을 통해 확인하였다.

Abstract: In this study, a blind carrier frequency offset (CFO) estimation method is proposed using the time-frequency symmetry of the transmitted signals of a weighted Fourier transform (WFrFT) communication system. Blind CFO estimation is achieved by focusing on the property that results in matching the signal waveforms before and after the Fourier transform when the WFrFT parameter is set to a certain value. Numerical simulations confirm that the proposed method is more resistant to Rayleigh fading than the conventional estimation methods.
