quadrotor + adabtive

感知准则函数，可以把前三组数据很好的分离出来(Perceptron criterion algorithm experiment)

Zernike moments calculation. Two functions, one for polynomial calculation and one for moments calculation

matlab file is use to just liquild volumn, now need you to help check it.

matlab进行偏最小二乘的四种分组方法(Four grouping method of partial least squares matlab)

说明：  这个是一个介绍OFDM原理的资料，对于初学者来说很好用(This is an introduction to the principle of OFDM data is useful for beginners)

1 通过实验，掌握多元正态分布的最大似然估计； 2 掌握多元正态分布下的最小错误率的贝叶斯分类； 3 对其他的参数估计有更深的认识。 (1 experiment, master multivariate normal distribution maximum likelihood estimation 2 multivariate normal distribution under the minimum control error rate Bayesian classifier 3 on the other have a better understanding of parameter estimation.)

该程序源代码实现了matlab通信系统性能的仿真，调制方式QPSK仿真(The source code implements communication system simulation matlab, modulation QPSK simulation)

说明：  PLL是一个锁相环模块，能得到波形的相角，从而实现同步信号的控制(PLL is a phase-locked loop module, waveform, phase angle, in order to achieve the control of the synchronization signal)
