matlab小波分析，振动信号处理，瞬态信号提取，故障分析(matlab wavelet analysis, signal processing, vibration, transient signal extraction, failure analysis)

modeling induction motor. very easy to use

msk MATLAB代码，可以实现msk调制,按IQ原理编写的(msk MATLAB code,msk modulation can be achieved,according to I,Q prepared in principle)

测试文本，选用著名的gettysburg这篇英文文本做为测试文本(Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters. In the end, the cosine similarity of texts is used to measure the similarity between the query and documents.)

此M文件是当进行批处理时，批量的查询所需的文件(When performing batch processing, batch files needed for the query)

在无线信道的理论基础上，分析了Suzuki信道模型的结构原理，介绍了利用正弦波叠加法构成高斯序列，从而建立Suzuki信道数学模型的方法，并通过Matlab软件对其进行了仿真。(In the theory of radio channel based on the analysis of Suzuki channel model structure principle, describes the use of sine wave superposition method constitutes a Gaussian sequence, thereby establishing a channel model Suzuki method, and through its simulation Matlab software.)
