这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is a space-time block coding based simulation design MIMO_OFDM communication systems. This system includes a QPSK modulation and demodulation demodulation, IFFT modulation, space-time coding and decoding, channel estimation based training symbol communication module.)

this is programming of matlab for watermark making.

一个用matlab写的特征挑选，大家试试吧！(Using matlab to write a feature of the selection, we give it a try!)

说明：  做过的一些关于A/D转换，can总线，USB等等，希望可以帮得了大家，具体说明，程序里面都有注解，谢谢(Done about A/D conversion, can bus, USB, etc. I hope you can help got the specific instructions and procedures which have a comment, thank you)

最小费用最大流问题是经济学和管理学中的一类典型问题。在一个网络中每段路径都有“容量”和“费用”两个限制的条件下，此类问题的研究试图寻找出：流量从A到B，如何选择路径、分配经过路径的流量，可以达到所用的费用最小的要求。(Minimum cost maximum flow problem is economics and management in a class of typical problems. Each path in a network has the " capacity" and " costs" two limiting conditions, such problems of trying to find out: Flow from A to B, how to choose the path, the path of the flow through the distribution can be achieved The use of the minimum cost requirements.)

关于基因序列上的比对问题 运用的方法是分支定界法 同时有贪婪算法作以比较(On the sequence alignment problem on the use of branch and bound method is a greedy algorithm for the same time to compare)

双曲线差分格式求解，包括一个双曲格式求截断误差及稳定性的例子，以及二维波动方程显格式、交替方向格式ADI1和ADIII格式的求解及matlab 程序，文件中附文档及题目的说明及其解法，易读易懂(Difference scheme for solving hyperbolic, including the format of seek a hyperbolic example of truncation error and stability, and significant two-dimensional wave equation format, alternating direction and ADIII format format ADI1 Solution and matlab programs, files, documents and questions in the attached instructions and Its solution, easy to read easy to understand)

基于MATLAB的ARIMA模型的源代码。ARIMA模型是自回归滑动平均求和模型，是时间序列分析模型，可以用于时间序列的预测。该代码实现了ARIMA模型的建模和谱分析过程(The ARIMA model based on MATLAB source code. ARIMA model is the sum of autoregressive moving average model is time series analysis models, can be used for time series prediction. The code to achieve the ARIMA models and spectral analysis of the modeling process)

通过对摄像镜头拍摄得到的图片进行失真复原，确定相应摄像头的固定失真系数，从而解决该摄像镜头的失真问题。(Image captured by the imaging lens distortion recovery, to determine the appropriate camera fixed distortion coefficient, so as to solve the problem of the distortion of the imaging lens.)

光纤陀螺输出误差的allan方差分析，基于K均值的PSO聚类算法,使用matlab实现智能预测控制算法。( allan FOG output error variance analysis, K-means clustering algorithm based on the PSO, Use matlab intelligent predictive control algorithm.)
