modulate_demodulate

区别于matlab自带的fft程序，为自主设计的myfft程序代码(Different from matlab' s fft own procedures for self-designed program code myfft)

对信号去噪，中间包括软阈值，硬阈值处理，garrot阈值，semidoft阈值处理，效果可以。(Of the signal denoising the middle soft threshold and hard threshold garrot threshold the semidoft threshold treatment effect can.)

Each trial uses 10000 bits is used for DQPSKModulator in Rician channel with K-factor value is 3

飞行器在某高度平飞时舵面偏角和飞行马赫数之间的关系(it describes the relationship between elevator declination and flight mach number，when flight fly on some hight.)

用减谱法进行语音增强，效果还不错。 读入语音，调整噪声水平即可。(Spectral method used by speech enhancement, the effect was not bad. Read into the voice, the noise level can be adjusted.)

关于短路仿真的一些源程序同时是有关多目标优化的源程序(Some source of genetic algorithm for multi-objective optimization is also the source)

fibo数列的一些有关MATLAB程序，，可以有效的清晰的实现Fibonacci数列的原理(something about Fibonacci math in MATLAB)

MIT归一化算法，基于MIT自适应律的模型参考自适应模型，对自适应律进行了归一化处理，消除输入对系统稳定性的影响(MIT normalization algorithm, MIT adaptive law based model reference adaptive model of adaptive law were normalized to eliminate the influence of input on system stability)

Locality Preserving Projections(LPP),局部保留投影，可以找出高维空间中的数据在低维空间中的投影，并保留了数据之间的相关性(Locality Preserving Projections (LPP), partial retention projection, you can find the data in high-dimensional space in a low dimensional space projection, and retains the correlation between data)

自己收集的matlab遗传算法的资料，耐心看完会有收获(Own collection of matlab genetic algorithm data, there will be harvesting the patience to read )
