this file try to make different level for OCTREE representation for 3D Objects

能进行BPSK信号通信系统的仿真，且有误码率的分析。(Can simulate BPSK signal communication system, and an analysis error rate.)

说明：  利用CMA算法实现4QAM信号的盲均衡，步长0.001，SNR=15，取得了较好的结果。没有实现相位补偿(Using the CMA algorithm to achieve blind equalization of 4QAM signals, with a step size of 0.001 and SNR = 15, good results have been achieved. No phase compensation)

通过MATLAB实现的打砖块游戏(breakout)，内含netlab人工神经网络工具箱(The implementation of a interesting game "breakout" using MATLAB, also a netlab toolbox of artificial neural network is included.)

先进PID，在MATLAB环境下编程，便于初学者进行交流，不足之处还望指导。(Advanced PID, in the MATLAB programming environment, easy for beginners to communicate, less than the guidance of the Office also hope.)

说明：  自己写的一个计算空间时频分布的程序，可知指定Cohen类分布类型WVD，CWD，PWVD，SPWVD，BJD(himself in a room when calculating the frequency distribution procedures, we can see Cohen category designated distribution type WVD, CWD, Wigner, SPWVD, BJD etc.)

这篇文章是通过改进的RD算法对大斜视角SAR进行仿真，通过仿真验证这种改进的算法是可行的。对研究雷达的人有帮助！(This article is simulation for large squint SAR by improving the RD algorithm.The result is demonstrated the improved algorithm is feasible。 It is useful for the poople that study the radar。)

灰色模型（GM)。如果一个系统具有层次、结构关系的模糊性，动态变化的随机性，指标数据的不完备或不确定性，则称这些特性为灰色性。具有灰色性的系统称为灰色系统。在灰色系统理论中，利用较少的或不确切的表示灰色系统行为特征的原始数据序列作生成变换后建立的，用以描述灰色系统内部事物连续变化过程的模型，称为灰色模型，简称GM模型。(GM 1 to 1)
