汉森1990年发表的协整检验以及面板门限模型的源代码,具有相当大的参考意义(Published in 1990, Hansen cointegration test and panel threshold model of source code, with considerable reference value )

采用matlab仿真OFDM，直接观察即可，无输入！将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。 

1.产生阶数为n的m序列。 2.测试阶数为n的m序列是否满足m序列性质。（与相应的m序列生成程序配合使用。实现检测效果）(1. Generate the order number n, m sequence. 2. Testing the order of n-m-sequence satisfies the nature of m sequences. (With the corresponding m-sequence generation program used in conjunction. To achieve detection results))

说明：  关于matlab基带msk调制的理解，并加之载波，并用GUI界面实现测试(msk test based on matlab)

灰色ＰＩＤ控制matlab仿真程序：主要包括连续、离散系统(gray PID control Matlab simulation program : including continuous, discrete systems)

Download the file town .jpg, which is a 1024×768, 256-grayscale image taken on a bright sunny day. The image was taken in the shadow of a building. As the result, the sunlight areas are glaring white and the shadow areas are dark and low contrast. Using the image enhancement techniques covered in class, increase the contrast and the brightness of the dark areas, and reduce the brightness of the sunny areas

铱星系统的空中接口采用QPSK调制，发送滤波器采用平方根升余弦滤波器，该程序是铱星系统的发送信号仿真模型。(Iridium air interface using QPSK modulation, transmit filter using square root raised cosine filter, the program is sending signals Iridium system simulation model.)
