COLLECTION OF TASK MICRO WAVE COMMUNICATION SYSTEM

说明：  利用matlab对平平腔中自在现模的进行了模拟(Using matlab to the flat itself is in the mold cavity has been simulated)

DES3200实验系统的模拟信号输出通道产生一个1KHz 的方波,然后利用信号输入通道对产生的方进行低通滤波,得到一个1KHz 的正弦信号，并使用CCS 的图形显示工具显示输入和输出的波形。这里我们使用的是一个46阶的对称结构的FIR低通滤波器，其采样频率Fs为25KHZ，通带截止频率 1KHZ，阻带截止频率为3KHZ，阻带衰减为-60dB。(DES3200 experimental system analog output channel generates a 1KHz square wave, and then use the signal input channels that produce low-pass filtering the square to get a 1KHz sinusoidal signal, and use the CCS' s graphical display tool shows the input and output waveforms. Here we use a symmetrical structure of 46-order FIR low-pass filter, the sampling frequency Fs to 25KHZ, passband cutoff frequency 1KHZ, stopband cutoff frequency 3KHZ, stop-band attenuation is-60dB.)

关于太空docking的一些论文文献，特地拿来共享一下 A number of papers on space docking literature, specially brought about sharing(A number of papers on space docking literature, specially brought about sharing)

it s combination from okumurra hatta pathloss and walfish ikegami model it can count pathloss in urban,suburban, and rural area

该程序适合于强散射环境下，并分析了收发端分别有nr和nt个天线情况下的系统容量。(In this programe a highly scattered enviroment is considered. The Capacity of a MIMO channel with nt transmit antenna and nr recieve antenna is analyzed.)

超声波扫查中，用线性阵元实现实现线性扫查，扫查体为自定义囊，对接收的回波数据进行hilber变换，获得其包络信息，在对包络信息进行对数压缩，用8为2进制数显示()

说明：  dsc单边带调制。功能是用10Hz的载波信号去调制频率为500Hz的基带信号，然后得到单边带调制信号(single-sideband modulation)

进行各种图形变换，很有用的程序。图象处理程序，包括对比度拉伸，傅立叶变换，离散余弦变换，维纳滤波等等。 (It s the function for DIP. Image processing involves changing the nature of an image in order to either 1.improve its pictorial information for human interpretation, or 2.render it more suitable for autonomous machine perception. )

经典粒子群算法的matlab实现。用函数进行测试实验，并给出算法寻优迭代的效果图(Classical PSO algorithm matlab. Experiments with test functions, and gives an iterative optimization algorithm renderings)
