to encode an LDPC code

用m序列过低通滤波器模拟产生带限高斯白噪声，m序列的长度足够长时功率谱特性接近高斯白噪声的特性。(M-sequence low-pass filter with analog band-limited white Gaussian noise generated, m length of the sequence is long enough the power spectral characteristics close to Gaussian white noise characteristics.)

It calculates the Power Delay Profile of a multipath environment. A detailed procedure is given

维纳滤波其设计，假设一个点目标在x，y平面上绕单位圆做圆周运动，由于外界干扰，其运动轨迹发生了偏移。其中，x方向的干扰为均值为0，方差为0.05的高斯噪声；y方向干扰为均值为0，方差为0.06的高斯噪声。(Wiener filter is designed, assuming a point target in the x, y plane around the unit circle in a circular motion due to external interference, its trajectory shift occurred. Which, x the direction of the interference of mean 0 and variance of 0.05 Gaussian noise y direction of the disturbance is zero mean Gaussian noise variance 0.06.)

说明：  一个高斯积分的例子，可能有点简单，不过还是给大家共享(Example of a Gaussian integral, may be a bit simple, but still to share)

基于matlab的智能材料-记忆合金的应用，是个不错的源代码，具有一定的价值(Matlab-based smart materials- the application of shape memory alloy, is a good source code, has a certain value)

关于小波去噪的程序，分为几种情况，适用于消除语音信号噪声(Wavelet Denoising of the program is divided into several cases for the elimination of the speech signal noise)

1采用遗传算法对男女生样本数据中的身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征进行特征选择，并基于所得到的最佳特征采用SVM设计男女生分类器，并计算模型预测性能（包含SE,SP,ACC和AUC ）。提示：可以用6位的0/1进行编码，适应度函数可以考虑类似 。(1 genetic algorithm for boys and girls in the sample data of height, weight, like math, like literature, like sports, like pattern recognition feature a total of six feature selection, design and use of SVM classifier for boys and girls based on the best features of the resulting and calculating prediction performance model (including SE, SP, ACC and AUC). Tip: 6 may be encoded with the 0/1, the fitness function may be considered similar.)

本代码用于仿真车辆在两条单向三车道道路上移动的情形，考虑到了加速度，超车，背景流量等(This code is used to simulate the movement of vehicles on two one-way three-lane roads, taking into account acceleration, overtaking, background traffic and so on)

子图像与母图像的匹配（子图像是母图像的一部分），用于判断子图是否在母图中(Sub-image and the master image matching (sub-image is the image part of the mother), used to determine whether the parent graph graph)
