一个非常实用的语音分帧程序，是用MATLAB写的(programme)

2D-DCT 压缩图像后，通过QPSK,AWGN信道编码传输后，IDCT解压缩回原始图像，适用于任何图像(Using DCT to compress the orginal image, I use zigzag program, quantization, dct compression, then change the vector to bineary bit to pass through the QPSK channel. And from the binary array, I use IDCT to reconstructe the orignial image. working perfectly.)

在MATLAB中实现用高斯消元法求解线性方程组!(In MATLAB to achieve using Gaussian elimination method for solving linear equations!)

说明：  判决导向的载波恢复算法，在PAM调制方式下实现。(Decision directed carrier recovery algorithms to achieve in the PAM modulation.)

基于蚁群算法的三维路径规划。在三维地图上寻找最优路径！(Ant colony algorithm based three-dimensional path planning. To find the optimal path on the three-dimensional map!)

二维FDTD程序，采用Mur吸收边界，实现了较好的吸收效果，可以用来与UPML吸收边界比较。(2D FDTD program, the Mur absorbing boundary to achieve a better absorption, can be used with UPML absorbing boundary.)
