讲述了OFDM的一些基本知识，包含框图，及OFDM的优缺点等。对OFDM有个全面认识。(OFDM about some of the basics, including block diagram, and the advantages and disadvantages of OFDM and so on. Have a comprehensive understanding of OFDM.)

音频系统，coding, modulation, AWGN, 通过最小距离探测码元，解码，播放。根据不同的SNR，测试在多小的SNR情况下，人耳能识别音频。(Audio systems, coding, modulation, AWGN, by minimizing the distance detection symbol, decoding, playing. Depending on the SNR, the test in the case of multiple small SNR, the human ear can identify audio.)

傅里叶变换可谓是应用于工程科学等各个领域，本文本内容少可以很好的匹配傅里叶变换各种问题(Fourier transform can be described as applied to engineering science and other fields, the contents of this article can be a good match fewer problems Fourier Transform)

说明：  This code is related to the course Digital Communications. It makes a simple communication system which uses AWGN and QPSK

gives an control scheme of the wind enery system

BPSK AWGN信道编码仿真源程序，适合初学者(BPSK AWGN channel coding simulation source, suitable for beginners)

网上下载的随机子空间程序修正版，保证可用(Download a random sub-space program revision to ensure that available)

说明：  基于模板的图像匹配，使用matlab实现，代码简洁， 有清晰注释(Template-based image matching, the use of matlab, the code is concise, clear notes)

SIFT DESCRIPTOR SOURCE CODE

对信号加窗，进行短时傅里叶变换，输出一个结构组，包含时间和频谱幅度(Signal windowed short time Fourier transform, and output a structure that contains the time and spectral amplitude)
