小波与熵的matlab代码，运行例程，需要的自己改一下(Wavelet and entropy)

基于聚类的K中心点算法，附带说明文档，代码简单高效，很好的利用了矩阵的代数运算。数学思想较为高深，但通过仔细研读说明文档和动手操作，matlab数学分析能力可以得到有效的提高(K medoids clustering annotated document, the code is simple and efficient, good use of matrix algebra operations. Mathematical thinking is more profound, but by carefully studying the documentation and hands-on the Matlab mathematical analysis ability can be effective to improve)

利用stft实现了跳频信号的跳周期估计 简单的进行了跳频信号的仿真，然后利用短时傅里叶变换对跳频信号进行分析，再对得到的时频矩阵提取时间平面，对时间序列去直流，进行傅里叶变换，最后实现得到跳周期。(estimates the hopping time of the sfh by stft )

关于心电图入门的基本知识，便于初学者学习和使用。(Getting Started on the basic knowledge of ECG, easy for beginners to learn and use.)

将OFDM技术运用在可见光通信的研究，并且把OFDM的高峰均比这一缺点进行了建设性的运用。(In particular, the use of OFDM (orthogonal frequency division multiplexing) for intensity modulation is investigated. The high peak-to-average ratio (PAR) in OFDM is usually considered a disadvantage in radio frequency transmission systems due to non-linearities of the power amplifier. It is demonstrated theoretically and by means of an experimental system that the high PAR in OFDM can be exploited constructively in visible light communication to intensity modulate LEDs. It is shown that the theoretical and the experimental results match very closely, and that it is possible to cover a distance of up to one meter using a single LED.)
