用R/S估算法计算时间序列的HURST指数(With R/S method to estimate time series HURST index)

UKF滤波方法，改方法比传统的卡尔曼滤波相比，主要是解决非线性问题(UKF filtering method, change methods than the traditional Kalman Filter, the key is to resolve the problem of nonlinear)

This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS). A high resolution time frequency distribution (TFD) is defined by com-bining FS computed using windows of varying lengths and chirp rates. The IF of individual signal components is then computed by applying a peak detection and component extraction procedure
