说明：  基于MATLAB的微分方程的界面设计，应付一下作业(Interface Design of Differential Equation Based on MATLAB)

自适应均衡器的仿真程序：在120hz信号下去处50hz干扰(adaptive equalizer Simulation : 120hz signal on the Department 50hz interference)

matlab code for space time encoding

本代码是关于用matlab算出两路信号的相位差(the code is calculated on the use of Matlab two signals phase difference)

数字滤波仿真程序，供大家参考！希望对大家学习有用！(digital filter simulation program, for your reference! We hope to learn useful!)

用于滚动轴承微弱故障信号的诊断的方法：最小熵反卷积程序、自适应消噪法处理轴承信号、美国西储大学轴承数据处理等5个源文件(Fault diagnosis for rolling bearing weak signal approach: minimum entropy deconvolution procedure, adaptive noise cancellation treatment bearing signals, Case Western Reserve University, United States bearing data processing five source files)

利用自适应陷波器来消除通信系统中的工频干扰。重点从LMS算法的步长因子、信号与干扰的频率差、参考输入的幅值和相位等几个方面讨论单频陷波器的滤波效果。另外，还以双频为例，讨论了多频级联型陷波器的特性，证实了经过两次滤波后，信号可被真实的恢复出来，且误差收敛趋于稳定。(The use of adaptive notch filter to eliminate the communication system frequency interference. LMS algorithms focus from step factor, the frequency difference signal and interference, refer to the input amplitude and phase of discussions on several aspects of single-frequency notch filter of the filtering effect. In addition, in order to dual-band, for example, discussed the multi-frequency cascade notch filter characteristics, confirmed the filtered twice, the signal can be restored out of true, and the error convergence stable.)

能量重心校正法，进行频谱的幅值修正，算法可以参见谢明、丁康老师的频谱分析文章。(Energy center of gravity correction method, the amplitude correction of the spectrum, spectrum analysis of the algorithm can be found in Xie Ming, DING Kang teacher article.)

提出了一个混沌系统,并对该系统的基本动力学特性进行了深入研究.得到该系统的Lyapunov指数、Lyapunov 维数,给出了Poincaré映射图以及时域图和相图.运用电子工作平台EWB软件对实现该新混沌系统的振荡器电路进行了仿真实验.经过数值仿真和电路系统仿真证实该系统与以往发现的混沌吸引子并不拓扑等价,属于新的混沌系统.(Presents a chaotic system, and the basic dynamic characteristics of the system were studied. Get Lyapunov exponent of the system, Lyapunov dimension, given the Poincar maps and graphs and time-domain phase diagram using electronic work platform EWB software for implementing the new chaotic system oscillator circuit simulation experiments through numerical simulation and circuit and system simulation confirmed that the system ever discovered chaotic attractor is not topologically equivalent, is the new chaotic system.)
