说明：  数字信号图象处理,对数字图象进行滤波和中值化(digital signal image processing, digital image filtering and the value of)

关于时钟同步timing synchronization 的例程，参数可重设，有注释(timing_syn.m timing synchronization )

子带自适应滤波器原理 很好的学习子带滤波器的外文教程 有MATLAB程序(Subband Adaptive Filtering Theory and Implementation Foreign-language tutorial sub-band adaptive filter principle of good learning sub-band filters have MATLAB program)

说明：  LDPC码的matlab实现，把解码的部分改过了，实验过很多次，符合理论要求，码长越长误码率越低(The implementation of LDPC code in MATLAB has changed the decoding part. It has been experimented many times and meets the theoretical requirements. The longer the code length, the lower the bit error rate.)

说明：  三电平逆变器模型,基于空间矢量算法，信号源为恒定三相交流信号经旋转变化得到控制脉冲信号(three level invetrer model)

光子晶体的能带图计算，其实质就是电磁本征值（复矢量场）的问题。利用平面波展开磁场，引入f(r)=1/eps(r)，再利用倒格矢G将f(r)展开，将两者代入光子晶体的支配方程，最后得到一个平面波展开的方法的线性方程组，最终转化为求解其特征值向量的问题。(Energy band diagram of the photonic crystal, its essence is the electromagnetic eigenvalues ​ ​ (complex vector field).The linear plane wave expansion magnetic field, the introduction of f (r) = 1/eps (r), re-use reciprocal lattice vector G will expand f (r), the two substituted into the governing equations of the photonic crystal, and finally get a plane wave expansionequations, and ultimately into solving the problem of its eigenvalues​ ​ .)
