FEM

说明：  数字信号处理中的DFT源代码，很实用，希望对大家有用(DFT Digital Signal Processing source code, it is useful, we want to be useful)

说明：  系统参数辨识，用增广最小二乘算法实现。对书中的程序进行了改进：由于噪声是未知的，虽然我们模拟了系统的随机白噪声，但进行辨识时必须对噪声进行估计，见程序45行和53行。(System parameter identification, with the extended least squares algorithm. Procedures for improving the book: Because the noise is unknown, although we simulate a system of random white noise, but to identify the noise must be estimated, see the program of 45 lines and 53 lines.)

说明：  LDPC bpsk调制，测试误码率性能。很值得下载的程序(LDPC bpsk Modulation test BER performance)

初始对准；用于导航制导与控制；给出了MATLAB程序(Alignment used for navigation guidance and control given MATLAB program)

用matlab很好模拟了一个单自由度质量-弹簧体系在阻尼作用下的衰减过程(Matlab simulation with very good quality of a single degree of freedom- spring system in the damping effect of the attenuation process)

采用不同算法编的一些模糊C-均值聚类（FCM）的matlab程序。(Compiled using a number of different algorithms of fuzzy C-means clustering (FCM) in the matlab program.)

QPSK仿真，Eb/N0=0:10,得出BER与Eb/N0的关系曲线，AWGN信道(QPSK simulation, Eb/N0 = 0:10, draw BER versus Eb/N0 of the curve, AWGN channel)

This program will give you image with different types of noise added to it and will show you effect and comparison of all

模拟透镜真实光路,厚的凸透镜，无小角度近似，使用真实光路追踪(Analog lens true optical path, the thickness of the lenticular lens, no small angle approximation, using the true optical path trace)

用子空间分解法求出时延估计，这种方法具有较强的抗噪声性能(Calculated using subspace decomposition delay estimation, this method has strong anti-noise performance)
