编写程序将含有20个数据的数组M分成两个数组：正数组P和负数组N，并分别统计两个数组的个数，显示在屏幕上。(Write a program containing the data array 20 is divided into two arrays M: positive and negative groups Array P N, and the number of two arrays statistics were displayed on the screen.)

根据书面协议的代码是3GPP LTE速率匹配的代码。该代码包含速率匹配交织在一起，重要的内容有点熟。(The code is on LTE 3GPP rate matching code based on written agreement. The code contains a rate matching intertwined, important content bit cropping.)

说明：  六旋翼飞机模型，包含六旋翼飞行器的电机模型和动力学运动学模型，输入为六个电机的油门(Six-rotor aircraft model, including six rotor vehicle motor model and kinetic kinematics model, input six motor throttle)

现有一个信号：x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的： 低通滤波器，滤除cos(2*π*n/3) 的成分，即想保留的成分为1+cos(π*n/4) 高通滤波器，滤除1+cos(π*n/4) 的成分，即想保留的成分为cos(2*π*n/3) 带通滤波器，滤除1+cos(2*π*n/3) 的成分，即想保留的成分为cos(π*n/4) 带阻滤波器，滤除cos(π*n/4) 的成分，即想保留的成分为1+cos(2*π*n/3) 1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器；画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。 (an existing signal : x (n) = a cos (* n/4) cos (2** n/3) design and digital filter to achieve the following objectives : low-pass filter, filter cos (2** n/3) the ingredients that want to retain an element of a cos (* n/4) high-pass filter, a filter cos (* n/4) components, namely to retain the element of cos (2** n/3) band-pass filter , a filter cos (2** n/3) components, namely to retain the element of cos (* n/4) band stop filter, the filter cos (* n/4) components, namely to retain the ingredients for a cos ( 2** n/3) 1. MATLAB order butterord except for the band Filter, using the order of the filter design butter; paint Filter magnitude and phase frequency of the corresponding filter system function H (z).)

ex9_12 二相编码信号的脉压处理，13位巴克码用于雷达的二相编码脉冲压缩中，由于巴克码具有好的自相关函数，所以其脉压结果很好(BPSK ex9_12 pulse pressure signal processing, 13 Barker Code for the two-phase coded radar pulse compression, as a result of Barker codes have good auto-correlation function, so its a very good pulse pressure results)
