2011年全国大学生数学建模山东省二等奖论文作品(2011 National Undergraduate Mathematical Modeling of Shandong province two prize paper works)

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.)

This package enables Gaussian process prediction with very large sample sizes with a much smaller computational burden than many existing methods.

特征提取算法 一篇经典的英文文献 介绍了一种新的算法 模式识别(Feature extraction algorithm，a classic English literature describes a new algorithm for pattern recognition)

创建一个高斯分布并画出其PDF曲线，文件设置为均值为0.其分散为1，参数可以调节(Create a Gaussian distribution, and Draw the PDF curve, the file is set to mean 0. The spread is 1, the parameter can be adjusted)

LTE系统中频率调度算法，利用该程序可以实现小区间干扰协调，非常适合初学者。(Frequency scheduling algorithm in LTE system, using the program can realize the inter cell interference coordination, very suitable for beginners.)

说明：  语音识别动态时间归正全过程的matlab程序，运行测试能出结果，希望对你们有用，实在没点数才把自己压箱底的东西拿出来,呜呜(Reformed voice recognition dynamic time the whole process of matlab program, run the test to the result, I hope helpful for you, only then it did not point out what their own bottom pressure, the hum)

matlab源码，实现利用霍夫变换的直线检测(matlab source code, line detection using Hough Transform)

matlab PID simple s model pid最简单的S模型，可以自己加入扫频信号，就可以看开环伯德图了(matlab PID simple s model)
