power_pwm

设计了一个扩频 系统，具有扩频解扩的功能。系统中采用的是瑞利衰落的信道。仿真的结果很好，系统的误码率很小(Designed a spread-spectrum system with spread spectrum despreading function. System is used in the Rayleigh fading channel. Good simulation results, the system bit error rate of the small)

SOM神经网络，可以进行特征提取和模式分类，特别是特征维数较多的情况(SOM neural network, feature extraction and pattern can be classified, more especially characteristic dimension of the case )

说明：  个人做的AM调制数字解调simulink仿真模块，大家多交流(The AM modulation personal digital demodulation simulink simulation module, we more exchanges)

说明：  地球物理中的一种方法--MT，基于matlab,利用有限差分方法(the method for MT,which is based on the matlab and infinite difference method)

Knowledge of the process noise covariance matrix is essential for the application of Kalman filtering. However, it is usually a difficult task to obtain an explicit expression of for large time varying systems. This paper looks at an adaptive Kalman filter method for dynamic harmonic state estimation and harmonic injection tracking.(Knowledge of the process noise covariance matrix is essential for the application of Kalm an filtering.
