通信原理matlab仿真中正交频分复用数字通信系统(Matlab simulation of communication theory orthogonal frequency division multiplexed digital communication system)

对混噪的信号进行处理实现自适应滤波器功能，从而可以把噪声很好地滤除掉，由描绘出来的滤波全系数变化曲线可以看出自适应滤波器的良好的滤波效果。(Mixed noise for adaptive signal processing filter function, which can filter out the noise well, portrayed by the curve of the filter coefficients can be seen the whole adaptive filter a good filter effect.)

光伏并网逆变器的仿真系统的S函数,能实现其的模拟仿真(PV grid-connected inverter simulation system S-function)

base implementation of MD4 family style digest as outlined in "Handbook of Applied Cryptography", pages 344 - 347.

说明：  里面涉及很多的混沌数据处理的算法，可以提供给大家使用(There are many chaotic data processing algorithms involved.)

模拟退火应用算法 可以用于一部分信号的处理(Application of simulated annealing algorithm)

space vector 2 level fast

I,Q通道的 噪声过程是高斯的的,而且是互不相关的,他的功率谱也是白的. 因为I和Q通道的噪声过程是高斯的,而且是互不相关的 我们可以得到他们是相互独立(Papoulis,1984). 最后,由于I和Q通道是独立的零均值高斯过程,因此可以推导出:复信号:I+jQ,幅度是瑞丽分布的,幅度的平放是指数分布的,相位角arctan(Q/I)是在(0,2π]上均匀分布(I Q Gaussian noise)
