短时能量与过零率，别人写的，好像是可以用的，大家试试啊(Short-term energy and zero-crossing rate, someone else wrote.maybe it can be used, please try it .)

bit error rate calculation

利用二维有限差分法对单脊波导TM模进行计算。通过调整网格数目观察计算结果的精度，可以设定出最优的网格数目，然后改变波导中脊的尺寸，观察最低两个TM模对应的截止频率的变化规律，最后给出对应的横截面电场、磁场分布图(The two-dimensional finite difference method to calculate the single-ridge waveguide TM mode. The optimal number of grid can be set by the accuracy of the adjustment of the calculation result of the grid number observed, and then change the size of the waveguide ridge observed the lowest two corresponding to the TM mode of the cutoff frequency of the variation, and finally to give the corresponding cross cross-section of the electric field, magnetic field maps)

主元分析法的C语言程序，主要用在降维的方面，也可用在信号处理，故障诊断。(Principal Component Analysis Method C language program, mainly used in dimensionality reduction, can also be used in signal processing, fault diagnosis.)

uses the message signal X to modulate the carrier frequency Fc (Hz) and sample frequency Fs (Hz), where Fs > 2*Fc. FREQDEV (Hz) is the frequency deviation of the modulated signal.

利用matlab，产生具有三个频率的跳频信号(the generation of jump-frequency signal)

壁障 粒子群算法 结构简单 内有详细说明(Barrier particle swarm algorithm is described in detail within a simple structure)

实现了chirp信号的分数阶傅立叶变换，表现出了其能量聚集效果，另外对单频、多频、高斯信号进行了分数阶傅立叶变换(The chirp signal Fractional Fourier Transform, showing the effect of its energy gathered addition of single-frequency, multi-frequency Gaussian signal Fractional Fourier Transform)
