본 논문에서는 정현파 가산 합성 모델을 기반으로 한 새로운 신호 주파수 추정 방법을 제시한다. 제안된 방법에서는 확장된 선형 예측(LP) 방법을 사용하고 짧은 레코드 길이에서 신호는 정상이고 잡음은 비정상이라고 가정하여 여러 지연 시간을 거쳐 신호와 잡음의 주파수를 추정합니다. 신호의 주파수는 다양한 지연에 대한 의존도에 따라 추출됩니다. 신호의 주파수 성분 수를 알 수 없는 경우에도 짧은 레코드 길이로 주파수 추정을 수행할 수 있습니다. 그리고 잡음이 있는 경우 신호의 주파수를 추정할 수 있습니다. 또한 제안된 방법은 더 적은 계산량과 높은 추정 정확도로 매개변수를 추정한다. 제안된 방법의 유효성을 확인하기 위해 시뮬레이션 결과를 제공한다. 제안된 방법과 합성 분석(ABS) 방법의 추정 정확도 비교는 해당 Cramer-Rao 하한과 함께 표시됩니다. 그리고 이 방법의 주파수 분해능도 표시됩니다.

Abstract: In this paper, we present a new signal frequency estimation method based on the sinusoidal additive synthesis model. In the proposed method, frequencies in both the signal and noise are estimated with several delay times by using an expanded linear prediction (LP) method, and assuming that the signal is stationary and noise is unstationary in short record length. Frequencies in the signal are extracted according to their dependence on different delays. The frequency estimation can be accomplished with short record length even in the case where the number of frequency components in the signal is unknown. And it is capable of estimating the frequencies of a signal in the presence of noise. Furthermore, the proposed method estimates the parameters with less computation and high estimation accuracy. Simulation results are provided to confirm the effectiveness of the proposed method. The comparison of estimation accuracy between the proposed method and the analysis by synthesis (ABS) method is shown with the corresponding Cramer-Rao lower bound. And the frequency resolution of this method is also shown.
