Face recognition using ATT database and PCA with matlab s princomp function

霍夫曼编解码程序，仿真了huffman编码和解码(huffman encode decode)

详细描述了cd4011的功能，并详细介绍了各个引脚，以及如何使用(Described in detail cd4011 features and details of each pin, and how to use)

NOAA网站AVHRR卫星数据绘图（SST）。数据选用原因:它本身是已经被处理过的27年（1982-2008）全球月平均数据，而且数据精度非常高，对于研究全球SST的气候态特征有较好的说服性；另外，选择2月与8月的数据，对描述海洋水温的平面分布更具有代表性。 (NOAA AVHRR satellite data mapping site (SST). Data Selection reasons: it is itself already been treated for 27 years (1982-2008) global average monthly data, and the data accuracy is very high, for the study of global climate SST state characteristics have better persuasive addition, February with the data in August, and the description of ocean water temperature plane distribution more representative.)

电压转换器，实现三阶电压转换，并且模拟了滇池充电(realize the charging for the battery by using three orders boost converter)

16QAM的调制与解调的实现，比较不错的代码，欢迎下载(16QAM modulation and demodulation achieve good code, welcome to download)

说明：  LogMAP译码算法,可用于递归卷积编码和非递归卷积编码的译码，代码质量高，供参考(<1> Log MAP decoder for RSC and NSC convolutional codes <2> Based on Lalit Bahl s original BCJR algorithm and its logarithmic version (Hanzo & Woodard). <3> Test-bench code is also included.)

利用Kaiser窗设计一个低通滤波器，通带参数、阻带参数、阻带衰减、通带纹波都可以进行调整。程序简单易懂，按照凯塞窗设计滤波器的步骤，非常容易理解，得到的参数可以在MATLAB命令窗口中看到。(Kaiser window design using a low-pass filter, pass parameters, the stopband parameters, stopband attenuation, passband ripple can be adjusted)

说明：  SCFDE的仿真，使用qpsk，还有相关文档(the simulation of SCFDE with QPSK)

OFDM系统仿真，简单的OFDM基本框架的一个仿真，matlab环境下实现的(it is good！)
