Novel fast motion estimation algorithm based on optimizing predictive motion vector

完成3gpp标准中LTE系统16QAM调制方式的编码，该附件为子函数，输入bit流即可(Completion of 16QAM modulation coding 3gpp standard LTE system, the attachment of Functions, input bit stream can be)

从wind采集期权数据并整理成矩阵形式，包括计算隐含波动率等(Collect options trading data, and make the data readable, calculate the implied volatility)

说明：  介绍了matlab中的数据归一化，并结合实例分析了归一化具体步骤及用ANN进行预测的方法。(Matlab introduced in the data normalization with examples of the normalized specific steps and methods used ANN to predict.)

常规PID控制器主要采用模拟PID控制器。这种控制器的控制规律是：根据给定值和输出值构成的偏差按比例、积分和微分通过线性组合构成控制量，对被控对象进行控制。(Conventional PID controller is used mainly analog PID controller. This controller is the control law: according to the given value and output value constitutes a deviation by proportional, integral and differential form by a linear combination of the amount of control, control of the controlled object.)
