代码说明：

说明：  本文分析了正弦波的 DFT系数 的结构通过DFT系数的相位信息, 可以对正弦波的频率作精确的估计，该算法与 iRfe 的算法性能互补, 结合这两种 算法, 得到了一种综合算法，计算机模拟结果显示, 本算法精度高, 而增加的计算量并不大, 并且容易硬件实现.(The structure of the DFT coefficients of a sine wave is analysed. A new accurate frequency estimator for asingle sinusoid is proposed by using the information obtained frormn the phase of the DFT coefficients. Its performance is com-plemental with Rife algorithm. So that synthetic approach is proposed. The simulation results indicate that this approach ismuch better than the DFT and some other fast methods at the cost of double FFT which is far less than the MLE in comput-e time.)
