查询词典 sinusoid

A new technique is presented in this paper for frequency estimation of single real sinusoid at a low computational cost using the real parts or imaginary parts of Fourier coefficient s.

提出了一种利用信号离散傅里叶变换系数的实部或虚部来构造频率修正项的新算法，算法只需傅里叶系数的实部或者虚部的最大值附近的3个DFT系数来构造频率修正项，避免了复数运算从而有效减少了运算量，同时算法的频率估计精度接近CRLB(Cramer-Raolow bound)。
