功率谱分析和matlab仿真 周期性分析(Power spectrum analysis and Matlab simulation )

用C或者matlab编写基2 FFT快速算法，输入点数是2的幂次方，序列视作既包含实部也包含虚部。要求一个函数计可以做正变换，也可以做反变换。编写输入序列，先进行正反向变换，得到离散频谱，再将离散频谱加载到输入端进行验证，从输出端获取序列，和原来的序列进行比较，看看是否相等。序列可随意设为2的幂次项！(Written by C or matlab base 2 FFT fast algorithm, the input power of 2 points is the sequence includes both the real part as the imaginary part is also included. Require a meter to do is change the function, you can also do the inverse transform. The preparation of the input sequence, first the forward and reverse transformation, discrete spectrum, discrete spectrum and then loaded into the input validation, access to sequence from the output side, and the original sequences were compared to see if equal. Sequence can be arbitrarily set to a power of 2 items!)

由低通数字变换为高通（带阻）数字频带的变换示例,附频谱特性图(by low-pass digital transformation of the high-pass (with resistance) digital bandwidth transform example, the map attached spectrum)

改程序主要对无线通信中的瑞利慢衰落通信信道进行了matlab仿真，可于仿真试验时进行调用。(Reform procedures for major wireless communications in the slow Rayleigh fading communication channel to carry out the matlab simulation, simulation tests can be carried out call.)

原信号分解成IMF后，用此脚本来计算此IMF的瞬时频率(After the original signal into IMF, use this script to calculate the instantaneous frequency of the IMF)

Radar 动目标MTI检测器 雷达MTI动目标检测，里面包含所有动目标检测的滤波器，很实用，有不同系数的滤波器进行比较，滤波器可以直接使用(Radar Moving Target MTI Detector Radar MTI moving target detection, which contains all moving target detection filters, is very practical. The filters with different coefficients are compared. The filters can be used directly.)

压缩感知算法工具箱，可以将压缩感知用于想用的任何算法。(The Compression Sensing Algorithm Toolbox allows you to use compression awareness for any algorithm you want to use.)
