这个文件包含了正弦调频信号的魏格纳威利分布以及经过平滑和加窗后的伪魏格纳威利分布和平滑伪魏格纳威利分布(This file contains a sinusoidal FM signal of the Wigner distribution and Na Weili after smoothing processing window of the pseudo-Wigner-Na Weili smoothed pseudo-Wigner distribution and the distribution of Na Weili)

Unscented Kalman Filter (UKF) exemplified on FitzHugh-Nagumo neuron dynamics. Voltage observed, currents and inputs estimated. FitzHughNagumo.m is the main program which calls the other programs. If you use these programs for your publications etc., please refer to H.U. Voss, J. Timmer & J. Kurths, Nonlinear dynamical system identification from uncertain and indirect measurements, Int. J. Bifurcation and Chaos 14, 1905-1933 (2004). I will be happy to email this paper, which contains a tutorial about estimation of hidden states and unscented Kalman filtering. For commercial use and questions, please contact me.

简单的信号处理程序,可以实现基本的z反变换。程序本身自带数据产生功能。(a simple signal process program)

二阶Butterworth滤波器, 可以直接用于数字信号处理，里面有输入输出说明，很详细(Second Order Butterworth Band-Pass Filter)

二维连续傅里叶变换二维连续傅里叶变换二维连续傅里叶变换二维连续傅里叶变换(Continuous two-dimensional Fourier transform two-dimensional continuous Fourier transform two-dimensional continuous Fourier transform two-dimensional continuous Fourier transform)

对WCDMA PCCPCH信道信号进行解码，输入是IQ空口信号，本程序会完成信号的解码直至CRC校验(Decode WCDMA PCCPCH channel. The input signal is air interface signal, the program will run until the CRC)

equal file can equalize comm signal.

说明：  鲸鱼优化算法(WOA)也是一种元启发式优化算法。一种新的模拟座头鲸狩猎行为的元启发式优化算法(鲸鱼优化算法，WOA)。目前的工作与其他群优化算法相比的主要区别在于，采用随机或最佳搜索代理来模拟捕猎行为，并使用螺旋来模拟座头鲸的泡泡网攻击机制。(Whale optimization algorithm (WOA) is also a meta heuristic optimization algorithm. A new meta heuristic optimization algorithm (whale optimization algorithm, WOA) is proposed to simulate the hunting behavior of humpback whales. The main difference between the current work and other swarm optimization algorithms is that the random or optimal search agent is used to simulate the hunting behavior, and the spiral is used to simulate the bubble net attack mechanism of humpback whales)
