ICA极大似然估计的自然梯度法仿真实例，并计算了串音误差( An experiment of ICA by MLE,including psnr)

该程序用于基于认知无线电NC-OFDM系统的仿真，用来计算信号的功率谱密度(The program for the NC-OFDM Cognitive Radio system simulation for calculating the power spectral density of the signal。)

基于人耳遮蔽效应谱减法的语音增强算法，matlab(Enhancement based on spectral subtraction ear shadowing speech，matlab)

遗传算法相关源码很多是很罕见的。遗传算法的方法。(Many GA-related source is rare. Genetic algorithm approach.)

MATLAB不提供现成指数拟合函数，一方面由于但可以轻松通过多项式拟合转化而来，但是使用上还是不如有一个函数方便，所以特写这样一样简单实用的函数(MATLAB does not provide ready-exponential fit function, by hand because it can be easily transformed a polynomial fit, but still not as good as there is easy to use a function, it is as simple close-up of such useful functions)

Characteristic Analysis of p-i-n Thin-Film Phototransistor Using Device Simulation.The optoelectronic characteristic of a p-i-n thin-film phototransistor is analyzed by comparing an actual device with device simulation. It is found using the actual device that the detected current is maximized when the control voltage is equal to the applied voltage.
