대칭 고차 차동 에너지 연산자를 기반으로 한 순간 주파수의 일반화된 공식이 제안되었습니다. 공식화의 동기는 일반적인 고차 차동 에너지 연산자가 순시 주파수 추정기에 사용될 때 시간에 따라 일부 주파수 정렬 오류가 있다는 것입니다. 일반화된 공식의 특별한 경우도 제시됩니다. 제안된 순시 주파수 추정기는 평균 절대 오차로 측정된 오차 성능 측면에서 기존 방법과 비교됩니다. 추정오차 성능은 대칭구조를 갖는 XNUMX차 순시주파수 추정기가 잡음이 없는 조건에서 가장 좋은 결과를 보인다. 시끄러운 상황에서는 대칭 구조의 XNUMX차 순시 주파수 추정기가 가장 좋은 결과를 생성합니다. 추정기의 유용성을 보여주기 위해 적용 예가 제공됩니다.

Byeong-Gwan IEM, "An Instantaneous Frequency Estimator Based on the Symmetric Higher Order Differential Energy Operator" in IEICE TRANSACTIONS on Fundamentals,
vol. E93-A, no. 1, pp. 227-232, January 2010, doi: 10.1587/transfun.E93.A.227.
Abstract: A generalized formulation of the instantaneous frequency based on the symmetric higher order differential energy operator is proposed. The motivation for the formulation is that there is some frequency misalignment in time when the ordinary higher order differential energy operator is used for the instantaneous frequency estimator. The special cases of the generalized formulation are also presented. The proposed instantaneous frequency estimators are compared with existing methods in terms of error performance measured in the mean absolute error. In terms of the estimation error performance, the third order instantaneous frequency estimator with the symmetrical structure shows the best result under noise free condition. Under noisy situation, the fourth order instantaneous frequency estimator with the symmetrical structure produces the best results. Application examples are provided to show the usefulness of the estimator.

AB - A generalized formulation of the instantaneous frequency based on the symmetric higher order differential energy operator is proposed. The motivation for the formulation is that there is some frequency misalignment in time when the ordinary higher order differential energy operator is used for the instantaneous frequency estimator. The special cases of the generalized formulation are also presented. The proposed instantaneous frequency estimators are compared with existing methods in terms of error performance measured in the mean absolute error. In terms of the estimation error performance, the third order instantaneous frequency estimator with the symmetrical structure shows the best result under noise free condition. Under noisy situation, the fourth order instantaneous frequency estimator with the symmetrical structure produces the best results. Application examples are provided to show the usefulness of the estimator.
