通信实验中BPSK,QPSK,2FSK,16QAM调制解调仿真代码，实现调制解调和星座图的观察.(Communication experiments BPSK, QPSK, 2FSK, 16QAM modulation and demodulation simulation code that implements the modem and observation constellation.)

The channel estimation algorithm is based on a subspace approach. The method works only for identifiable STBCs (excluding >=1-rate STBCs). See publication [1] for more detail about the algorithm and the identifiability conditions. The zip file contains three m files. - space_time_coding.m (perform space time coding) - subspace_channel_estimation_STBC.m (channel estimation) - one_shot.m (show an example) To use these files, extract the three files in the same folder. Then, call the script one_shot in the matlab command window. Reference: [1] Ammar, N. Ding, Z.

生成小世界网络的Matlab程序，比较好，很多人都在用这个(Generate small-world network Matlab program, better, a lot of people are using this)

用于确定分析蛋白质序列上编码区的一个程序，算法虽然有点过时，但还有些参考价值。(Is used to determine the protein sequence analysis of the coding region of a program, algorithm though a bit outdated, but some reference value.)

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)

This code is used to simulation of bed load transport in two phase flow domain.
