用matlab编写的信号处理之QPSK调制与解调程序,均衡,OFDM仿真,小波变换,卡尔曼滤波等等14个程序源代码(Written by matlab signal processing of the QPSK modulation and demodulation process, a balanced, OFDM simulation, wavelet transform, Kalman filtering, etc. 14 source code)

说明：  关于Lorenz函数处于混沌时的图形，包括建立Lorenz函数集画图程序(about Lorenz)

说明：  这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)

Pass the Images Through Optics -- Use a Gaussian "Aperture Function" This code segement can use a measured aperture function just as easily - simply replace the next five lines by "load measured_aperture" where measured_aperture is the measured function strored in ASCII and the data stored in the file measured_aperture.mat is a MATLAB .mat file that contains the matrix apfunction. (in MATLAB type "help load" for how to use load and look at the c and fortran code that shows how to read and write MATLAB .mat files). (Note: When the Point Spread Function is Gaussian, then so is the Aperture function) To simulate the effect of the tracker optics, each of the movie frames is now blurred using a 2-D FFT (Fast Fourier Transform). The first frame of the resulting image is shown in Figure 1.

一个交交变频电路，没有DClink中间环节，(A cycloconverter circuit, not DClink intermediate links,)

利用c语言编写的，在matlab环境下运行mex函数可以生成动态的dll库，可以用来计算图像区域的梯度向量直方图特征。(Use c language, in the matlab environment running mex function can generate dynamic dll library that can be used to calculate the gradient vector histogram image area.)

猴子摘桃海滩上有一堆桃子，五只猴子来分。第一只猴子把这堆桃子凭据分为五份，多了一个，这只 猴子把多的一个扔入海中，拿走了一份。第二只猴子把剩下的桃子又平均分成五份，又多了 一个，它同样把多的一个扔入海中，拿走了一份，第三、第四、第五只猴子都是这样做的， 问海滩上原来最少有多少个桃子？(Peach Monkeys on the beach there is a pile of peaches, five monkeys for points. The first monkey peach credentials this heap is divided into five copies, more than one, the monkey to more than one thrown into the sea, took a. The second monkey the rest of the peaches and what the average is divided into five, and there are one, and it is likewise more than one thrown into the sea, took a third, fourth, fifth monkeys are actually doing that , the question on the beach for at least the number of the original peach?)

细胞神经网络，简称为CNN，由于其能够产生混沌吸引子，而被广泛应用于加密系统中，本代码为画出CNN的超混沌吸引子。(Neural networks, referred to as CNN, due to its ability to generate chaotic attractor, and is widely used encryption system, the code for drawing CNN super chaotic attractors.)
