说明：  TASI法相机标定，实现一阶径变系数和焦距F的求解。误差为5个像素(TASI camera calibration method to achieve first-order path coefficient and focal length F of the Solution. Error of 5 pixels)

集群通信随机接入仿真，主要是针对集群用户接收与普通用户接收的对比（直方图），集群用户正确接收率、普通用户接收率，总的误判率。(Cluster communication random access, cluster users and ordinary users access contrast (histogram), cluster users receive the accuracy and ordinary users receive the accuracy rate of miscarriage of justice problems.)

matlab关于有限元的一些知识，希望对大家有帮助。(Some of the finite element matlab knowledge, we want to help.)

对信号加窗，进行短时傅里叶变换，输出一个结构组，包含时间和频谱幅度(Signal windowed short time Fourier transform, and output a structure that contains the time and spectral amplitude)

说明：  ESPRIT方法进行DOA估计，各种参数见程序内部的参数设置，只是简单的ESPRIT程序，而非修正的ESPRIT方法(ESPRIT DOA estimation methods, see the program within the parameters set of parameters, but simply the ESPRIT program, rather than the ESPRIT method of correction)

此程序的功能是用自相关法求使信号s均方预测误差为最小的预测系数 算法为Levinson-Durbin快速递推算法 (The function of this procedure is signal s with autocorrelation method for the prediction of the minimum mean square prediction error coefficient algorithm for Levinson- Durbin quick recursion method)

实现FFT谱分析，并进行全相位FFT谱与传统FFT谱的比较(To achieve FFT spectrum analysis, and comparison of all phase FFT spectrum with the traditional FFT spectrum)

该程序主要仿真了正交频分复用系统，然后加上均衡器，最后仿真分析了正交频分复用系统结合均衡器后整体的系统性能。(The program is mainly the simulation of orthogonal frequency division multiplexing system, then add equalizer, finally simulation combined with orthogonal frequency division multiplexing system are analyzed after the equalizer overall system performance.)

卫星链路的计算，包括上下性链路噪声，互调噪声，可计算误码率(The calculation of satellite links, including links from top to bottom of noise, intermodulation noise, Computable error rate)
