ofdm的详细仿真，包括信道，多径，及多部分的波形，详细的说明(OFDM detailed simulation, including channel, multi-path, and multi-part of the waveform, a detailed description of)

高级图像显示，利用Matlab原程实现，运用面广，可以显著提高图像的质量(High image shows that the use of Matlab realize the original way, using a wide range, can significantly improve image quality)

说明：  1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图 (1. Using Matlab generated sine wave, rectangular wave, as well as the white noise signal, and display their respective time-domain waveform of Figure 2. FFT to transform, showing their frequency spectrum, including sampling rate, frequency, data length of 3-on-demand. Made of the three signals in root-mean-square maps, power maps, as well as the number of root-mean-square map 4. Fourier Transform IFFT with the restoration of signals, and displays the sinusoidal signal the resumption of time-domain waveform)

该代码为用matlab编写的训练神经网络拟合典型函数曲线的经典程序。(The code is made for training neural network to fit the classical function profile.)

生成一个随机序列，然后对其进行HDB3编码，最后对其解码，显示出来(Generating a random sequence, then subjected HDB3 encoding, and finally decodes, displayed)

用matlab编写的软件，用于人脸检测的一个很好用的软件，可以自己随便找一幅图像进行测试。(Matlab software used to prepare for the face detection software used in a very good, can not find an image for testing.)

This file is a literature survey of password authentication

说明：  sift提取特征点、描述子、最后进行匹配。(sift ：feature point，descriptor， matching。)

matlab学习的相关例程，供大家学习参考，希望多多交流，共促进步！(Matlab learning related routines for people to study, reference, hope more exchange, total promote steps)
