远程监控系统，具体不知道 ，刚接触，好多不懂，所以才来找学习的软件(Remote monitoring system, specifically do not know, are new, many do not understand is why they come to learn the software)

大斜视角下，点目标的距离多普勒算法(RDA,Range_Doppler Algorithm)仿真，Matlab语言。(Range_Doppler Algorithm,Matlab)

单相H桥多电平逆变器控制电路，基于matlab2014b环境下编写(Single-phase H-bridge multi-level inverter control circuit, based on the following written matlab2014b environment)

Bairstow s approach is to use Newton s method to adjust the coefficients u and v in the quadratic x2 + ux + v until its roots are also roots of the polynomial being solved. The roots of the quadratic may then be determined, and the polynomial may be divided by the quadratic to eliminate those roots. This process is then iterated until the polynomial becomes quadratic or linear, and all the roots have been determined, bisection and other

MATLAB program for speech signal recognition using lpcc (Linear Predictive Cepstral Coding) one of the method for the pick up of speech character.

说明：  车牌倾斜校正程序，将车牌边界与图像边界不平行的图像进行旋转，使其平行，可用于车牌识别。(Plate tilt correction procedure, the plate boundary is not parallel with the image border to rotate the image, a parallel can be used for license plate recognition.)

This is a direct torque control of induction motor

说明：  利用小波分析具有时频局部化特性和熵能对系统状态进行表征的特点，将小波分析和熵结合起来，定义了3种小波熵（小波能谱熵、小波时间熵、小波奇异熵），并给出其算法，揭示了这3种小波熵对系统故障表征的机理，对两种理论信号和基于PSCAD/EMTDC仿真的输电线路故障信号(Based on the characteristics of time-frequency localization of wavelet analysis and entropy energy to represent system state, three kinds of wavelet entropy (wavelet energy spectrum entropy, wavelet time entropy and wavelet singular entropy) are defined by combining wavelet analysis and entropy, and their algorithms are given. The mechanism of these three kinds of wavelet entropy for system fault characterization is revealed. The results show that the three kinds of wavelet entropy can be used to characterize system fault Road fault signal)

扰码的产生MATLAB程序。用于移动通信等领域的扩频加扰，区分用户。(Scrambling code for selecting the MATLAB program. For mobile communications in areas such as spread spectrum scrambling, to distinguish between users.)

MATLAB及在电子信息课程中的应用.感觉很有用,本来也不花钱,有想用的来拿吧(MATLAB and electronic information in the application of the curriculum. Feeling very useful, would have no money, there are来拿want it)
