UWB，超宽带信号分析必用的子函数，第19部分！(UWB, ultra-wideband signal analysis will be used to Functions, Part 19!)

生成矩阵和校验矩阵的生成在MATLAB语言下的实现(Generated matrix and calibration matrix generated in the MATLAB language to achieve under)

以计算样本点到聚类中心的距离为例，学到matlab中矩阵在加权指数,迭代次数和误差的相关应用(Sample points to calculate the distance to the cluster center, for example, learn matlab in the matrix in the weighted index, the number of iterations and errors related applications)

this is a a assembly code for multipattern running lights

QFSK加高斯噪声后，在0-10dB信噪比下，误码率曲线绘制(After QFSK plus Gaussian noise at 0-10dB SNR, BER curves plotted)

将背景音乐（交响乐）中的摩斯电码找出并分离出来(morse_code_sound.wav is a mono (1-channel) 11,025 samples per sec, 16-bits per sample, WAV file. There is a morse code signal within the audio file, you should be able to hear it in the background, but it is not very audible (able to be heard). Write a Matlab program to analyze the wav file and determine the narrow range of frequencies occupied by the morse code sound. Then separate the morse code sound into a separate file and the music into a separate file. Write out the separated morse code and the separated music to separate wav files titled your_name_morse.wav and your_name_music.wav)

说明：  MATLAB编写的中值滤波函数，可用于一维数据的平滑处理。(The median filter function written in MATLAB can be used for smoothing one-dimensional data.)

对于一幅输入图像，将产生一幅输出图像，输出图像的每个像素点的灰度值由输入像素点决定，将感兴趣特征的对比度扩展使之占据可显示灰度级的更大部分。使一输入图像转换为在每一灰度级上都有相同的像素点数，均衡化会减少灰度级数。大多数自然图像由于其灰度值分布集中在较窄的范围之内，引起图像细节不够清楚。采用直方图修正后可使图像的灰度间距拉大或使灰度均匀分布，从而增大了反差，使图像细节清楚，达到增强的目的。(For an input image, will produce an output image, the output image gray value of each pixel from the input pixel decided to expand interest in the contrast of features to make it account for more gray levels can be displayed most. Make an input image is converted to grayscale in each pixel have the same points, equalization will reduce the gray series. Most natural images because of their gray value distribution concentrated in a narrow range, causing the image detail is not clear enough. Make the image histogram revised by the gray space widening or so gray uniform distribution, thereby increasing the contrast between the image details clear objective to achieve enhanced.)
