说明：  经典的同步算法，即最大似然同步算法，对于开发3G系统很有效( a good synchronization program named as ML(the maximum likelihood method),it is useful for you to develop the 3G system.)

说明：  LDPC码的BP算法译码MATLAB程序(LDPC decoding algorithm BP MATLAB)

ofdm基带传输，信道编码，QPSK调制，卷积编码(the OFDM baseband transmission, channel encoding, QPSK modulation, convolutional encoder)

本程序是一个数据预处理的程序，首先通过KL变换将数据进行一次降维，然后通过LDA对数据进一步降维(This program is a data preprocessing procedure, first by a KL transform data dimensionality reduction, then the data further by LDA dimensionality reduction)

墙角在对流边界情况下的温度场模拟计算程序。用户输入墙角两侧的流体主流温度，对流换热表面传热系数，设定墙角以及计算网格尺寸后，程序可以通过迭代求解墙体的温度场并以矩阵和三维图像的形式输出。(A simulation program for the temperature field of the wall corner under the convective boundary condition. After entering the mainstream temperature of the fluid on the sides of the corner, the heat transfer coefficient of the convection heat transfer surface, the setting of the wall angle and the mesh size, the program can solve the temperature field of the wall iteratively and output it in the form of matrix and three-dimensional image.)
