spwm technique, which iam trying to solve but didnt get solution

EOF：经验正交函数分解!“实现时空场的离”具体可以参考黄嘉佑老师的《气象统计分析与预报方法》!这是来自“李建平”老师的EOF分解程序(EOF: Empirical Orthogonal Function! Specific Huang J. teacher meteorological statistical analysis and forecasting methods " can refer to" spacetime off! " Li Jianping teacher from EOF decomposition process)

This file has the code for GMM classification technique

说明：  pmsm的观测器matlab函数，基于ESO理论编写(Matlab function of PMSM observer, based on ESO theory)

给出BCH编码和译码的原理 以及解决方案，特别是仿真的一种解决方案，值得参考。(BCH coding and decoding given the principle, as well as solutions, in particular the simulation of a solution, it is also useful.)

it is phae shift keying

这是一个用matlab软件基于灰色系统理论编写的预测程序，改程序的通用性很高(This is a Matlab software written based on the gray system theory prediction program, the high versatility of the reform program)

本设计主要对4PSK调制方式的信号，利用MATLAB的m文件进行最佳接收机的设计与仿真。对输入的叠加噪声的4PSK调制信号进行接收，利用相关解调器来实现信号解调，及最大似然准则来实现检测器。在相关解调器中，接收信号分别与基函数 和 相乘再积分。在检测器中，利用相位来判断输出，从而最终得到接收的数据。采用随机二进制数通过4PSK调制后叠加高斯白噪声再对设计的接收机进行测试，从测试的结果可看出，在信噪比大于-8dB时，误码率为0，说明该接收机较好的实现了抗噪声性能。(The design of the main 4PSK modulation mode of the signal, the use of MATLAB m file for the best receiver design and simulation. The 4PSK modulated signal of the input superimposed noise is received, and the demodulator is realized by the relevant demodulator, and the maximum likelihood criterion is used to realize the detector. In the associated demodulator, the received signal is multiplied by the basis function and multiplied by the basis function. In the detector, the output is judged by the phase, and finally the received data is obtained. Using the random binary number through 4PSK modulation after the superposition of white noise and then the design of the receiver to test the test results can be seen in the signal to noise ratio greater than-8dB, the bit error rate is 0, indicating that the receiver is better The realization of the anti-noise performance.)

绘制不同函数曲线的用户界面，可控制小球运动速度的用户界面达到多样性，还有一些关于图像的频率格式转换的操作(Function curve to draw different user interface, can control the ball speed to achieve diversity in the user interface, and some on the frequency of the image format conversion operations)

最优化实验，用的是MATLAB，题目不是很难主要是练习用，学会对实际问题进行数学抽象。 掌握常用的最优化算法。 运用相关数学软件设计程序进行求解。 (optimization experiments, using the MATLAB, the main topic is not difficult to practice with. learn to practical issues abstract mathematics. Master of the most commonly used optimization algorithm. Related to the use of mathematical software for the design process.)
