matlab_ch5

this is a code for matlab

nrzi viterbi with snr 2 , 4 ,6, 8 dB and calculating BER

说明：  颜色矩的计算 color Moment，图像处理特征提取(color Moment)

fingerprint feature extraction

To calculate the Bit Error Rate (BER)of AWGN channel for a given range of SNR in MATLAB

说明：  matlab可实现代码，学习用比较好。可以实现基于matlab的蚁群算法。(Matlab can achieve code, learning with better.Ant colony algorithm based on Matlab can be realized.)

输入为JPG格式图像，通过小波模极大值提取图像边缘，共分3级进行提取，输出包括原图像边缘检测结果和不同级别小波边缘图像。(JPG format input image, the wavelet modulus maxima extracted image edge extraction is divided into three, the output includes the original image edge detection results and the different levels of wavelet edge image.)

Program made in matlab for calculating matrices trough elemental matrix methood.

利用OptiSystem仿真软件对光纤色散进行仿真和分析。通过对初始时的脉冲波形、经过20km非线性色散光纤或的脉冲波形，理解光信号在传输过程中的色散问题。(Use OptiSystem simulation software simulation and analysis of optical fiber dispersion.Through the initial pulse waveform, after 20 km nonlinear dispersion fiber, or pulse waveform, understand the dispersion problem in the process of optical signals in the transmission.)

有关多采样率转换问题，本文介绍了多采样率转换的MATLAB实现以及基础理论。(Multi-sample-rate conversion on the issue, this paper introduce a number of sample-rate conversion of MATLAB as well as realize the basis of the theory.)
