m序列应用于跳频通信系统，给出了跳频序列的生成函数，并给出高斯白噪声下和多用户干扰下的误码率曲线。(m sequence used in frequency hopping communications systems, frequency hopping sequences give the generating function, and give under the white Gaussian noise and multi-user interference of the bit error rate curve.)

与《通信天线建模与matlab仿真分析》配套的光盘("communications antenna matlab simulation modeling and analysis " supporting the CD-ROM )

避障程序演示，运用遗传分析法。。。。。。(Obstacle avoidance program demonstrates the use of genetic analysis.......)

这是《Windows高级编程第五版珍藏版》一书中的源码，11-23章，由于源码太大所以分开上传，这是下(This is the " Windows Advanced Programming Fifth Edition Collector' s Edition," a book source, 11-23 chapters, due to too much so upload separate source, which is under)

梁元有限元分析源码（用matlab语言编写而成）(Liang Yuan-source finite element analysis (prepared by using matlab language))

matlab语言的PCA分类程序，功能强大，使用方便，故共享之(matlab language PCA classification procedures, powerful, easy to use, so to share the)

如果对通信系统的同步或者频偏感兴趣的话，这将是一个很好的学习代码，我花了很长时间写的(Communication system synchronization or frequency offset of interest, this will be a good learning code, I spent a long time to write)

说明：  实现二维的避障路径规划，自己规划障碍物形状和选择点，利用轮盘赌迭代出最优路径。(Realizing two-dimensional obstacle avoidance path planning)
