本程序实现随机数的产生和在相同调制方式下功率谱比较(the program of random number generation and modulation in the same way under the power spectral comparison)

主动式反孤岛效应方法中的主动频率偏移法，通过matlab中的Embedded function编写的验证函数(Active anti-islanding methods active frequency offset method, through the Embedded function matlab written verification function)

FACE DETECTE AND RECOGNITON AND FISHERFACE AND IGENFACE

用Baum-Welch算法来迭代估计一个隐马尔科夫模型（HMM）的初始状态概率分布以及其状态转移概率矩阵。其中文件有mainfile_B_W.m为主函数，Baum_Welch.m为Baum-Welch算法迭代函数，Forward_variable.m与Backward_variable.m与Gamma_variable.m与Ksi_variable.m是需要计算的四种因子，B_pdf.m为混淆散射概率密度函数。(It s Baum-Welch algorithm for iteratively estimating the initial states probability distribution and state transition probability matrix. In the folder, "mainfile_B_W.m" is the main function, and "Baum_Welch.m" is the iteration Baum-Welch function. Also these four file "Forward_variable.m " "Backward_variable.m" "Gamma_variable.m" "Ksi_variable.m" are used for calculating crucial factors. "B_pdf.m" is the emission probability distrubution function.)

本程序比较了LS(最小二乘）和最小均方误差准侧下OFDM信道估计的误码率，给出了LS及MESE实现的源程序，是信道估计初学者的理想参考资料(This procedure compares the LS (least squares) and minimum mean square error of quasi-lateral channel estimation of OFDM bit error rate, given the realization of the LS and the MESE source, channel estimation is the ideal reference for beginners)

a var controller is presented.

自己编的，利用MATLAB进行DPSK和PSK编码，可用于数字通信的课程学习中。(Own, and the use of MATLAB for DPSK and PSK encoding, digital communication can be used to study in the curriculum.)

自己写的卷积编码MATLAB程序，已将验证过了，没问题，可以用的哈！(Wrote it myself, convolutional coding MATLAB program has been verified, and no problem, you can use Ha!)
