介绍了 Cohen类双线性时频分布并针对交叉干扰项影响无法完全消除的问题进行了重排时频变换以提取及分辨 含有白噪声和窄带周期干扰的局部放电信号。处理仿真和现场检测到的局部放电超声信号时根据白噪声和窄带 周期干扰信号在时域上的平稳性特性发现重排 Cohen类时频变换方法不仅可以很好地将局放信号和背景噪声以 及窄带周期干扰信号分辨开来,而且大大减弱并抑制了交叉干扰项的影响,保持了更高的时频分辨率和时频聚集 性,从而验证了重排 Cohen类时频变换方法的有效性。 (In order to express the partial discharge ( PD) information of gas insulated switchgear ( GIS) in time-frequency domain, weintroduced theCohen? s class bilinear time-frequency distribution and its reassigned time-frequency transform method to pick up and distinguish theultrasonic signals in field from the whitenoises and narrow band periodic interference signals using the acousticemission ( AE) technology. After the processing of the simulated and PD ultrasonic signals in field, and according to the stationary feature of white noises and narrow band interference signals, wedraw a conclusion that the reassigned time-frequency distribution method can not only distinguish thePD signal from back ground noises and narrow band interference signals, but also decrease and restrain the influenceof cross-items, and acquire better time )

我现在主要研究的是非负矩阵在特征提取方面的工作，上传几个我阅读的外国文献的，书籍源代码，在代码中有相应的文献或综述。我就上传一个low rank NMF的。压缩包里有9个文件。(I now mainly studied non-negative matrix feature extraction work, and upload a few I read foreign literature, books source code, there is a corresponding review of the literature or in the code. I' ll upload a low rank NMF' s. Compression bag has nine files.)

此程序描写了一个猜数过程，系统在给定范围内随机生成一个数，如何根据提示在较少的次数内才对这个数。(This procedure describes a guessing process, the system randomly generated within a given range of a number of tips on how to lower the number of times the number of fishes.)

用MATLAB生成bpsk信号，并通过AWGN信道的仿真。(MATLAB bpsk signal generation, and through the AWGN channel simulation.)

振动理论中的主动控制程序，对于振动方面的学习有一定的帮助。(The active control of vibration theory program, the vibration aspects of learning have some help.)
