Implements a data-driven noise tracking algorithm suitable for nonstationary noise sources.

运用FDTD算法计算了喇叭天线的近场分布，有一定的参考价值。(Use the FDTD algorithm to calculate the the horn antenna near-field distribution, there is a certain reference value.)

Using MATLAB on a Orthogonal Frequency Division Multiplexing, and to map out the bit error rate simulation results.

Matlab GUIDE 编程使用手册（中文）(Matlab GUIDE program introduction)

CRC 校验的基本思想是利用线性编码理论，在发送端根据要传送的k 位二进制码序(crc)

用Fourier变换求信号的功率谱(分段周期图法)(Calculate the power spectrum of signal using Fourier transform method)

本例是使用kalman filter作为状态观测器，对直流无刷电机的状态进行观测。从结果可以看出，对状态估计的效果非常的好(This example is the use of kalman filter as an observer state, the state of brushless DC motors were observed. As can be seen the results of state estimation of the effect is very good)
