说明：  分析了现有船舶自动避碰系统的不足,提出了基于人工势场法的船舶自动避碰系统. 根据 船舶的操纵特性,建立了引力场和斥力场函数,实现船舶自动避碰航行的合力和方向. 在电子海图 所建立的仿真环境中,验证了人工势场法可用于船舶自动避碰系统中.(Analysis of existing ships lack of automatic collision avoidance system is proposed based on artificial potential field method automatic collision avoidance system for ships. According to the ship maneuvering characteristics, the establishment of a gravitational field and the repulsive force field function, automatic collision avoidance to achieve ships sailing together, and direction. in the electronic chart of the simulation environment created to verify the artificial potential field method can be used to ship automatic collision avoidance system.)

这是一个matlab周期图法与BT算法的仿真代码(This is the periodogram and BT algorithms in a Matlab simulation code)

这是HEED协议的源代码，根据论文的描述缩写，基本实现了论文的功能，但是有些微小的出入。(HEED protocol source code, according to the paper' s description of abbreviations, the basic functionality of papers, but some minor discrepancies.)

分析psk调制与解调的函数，并有误码率分析(psk)

UKF滤波方法，改方法比传统的卡尔曼滤波相比，主要是解决非线性问题(UKF filtering method, change methods than the traditional Kalman Filter, the key is to resolve the problem of nonlinear)

用于编写分段函数，方便实用，简单，可以直接复制套用。(Preparation of sub-function)

对应书籍为《复杂非线性系统自适应动态优化》课本第六章例子的程序，讲述单网络的自适应动态优化(Corresponding books as " complex adaptive dynamic optimization of nonlinear systems" textbook example of Chapter VI of the program, about a single network adaptive dynamic optimization)

说明：  LDPC编码的matlab编程 很有参考价值(LDPC coding was useful matlab programming)

用Matlab程序测试一个模数转换器ADC的信噪比SNR和有效位数(use matlab to test SNR of a ADC)
