摘要
回顾了四参数正弦波曲线拟合方法及相关问题的研究进展,包括拟合算法的研究,拟合算法的比较研究,拟合算法的评价研究,以及不同条件下拟合算法的研究进展.针对拟合算法的误差界研究进展以及如何降低拟合误差的滤波技术进展情况也进行了专门介绍.另外介绍了相应的单参数、双参数、三参数正弦波拟合研究进展状况以及多频正弦参数估计技术进展状况.
Four-parameter sine wave curve-fit methods and the related researches are reviewed, including curve-fit algorithms, algorithm evaluation and study progress. The paper introduces the study on error bound of curve-fit and the filtering methods for decreasing curve-fitting error. All of the singleparameter, double-parameter, three-parameter, and four-parameter sine wave curve-fit methods are discussed. The multi-tone sine wave parameter evaluation technologies are also reviewed.
