opnet的培训课件，三天的培训内容，包括了概念介绍，建模，调试，以及两个实例。(opnet training courseware, training days, including the introduction, modeling, testing, and two examples.)

LTE-Advance信道预编码矩阵构造的matalb仿真程序，具有很好的使用价值。(LTE-Advance-channel pre-coding matrix simulation program constructed matalb has good value in use.)

it is the project developed in matlab to remove noise

说明：  利用压缩包内的5和函数产生PPM调制的UWB信号，信号波形为高斯二阶导函数。重复编码次数，TH码长度范围，波形形成参数alpha等参数均可以改变(use compressed within the five functions to generate PPM and the UWB signal modulation, Waveform second derivative of the Gaussian function. Repeat code number, TH code length, alpha waveform parameters such as formation parameters can be changed)

用一个仿真实例来说明子空间辨识算法下的Matlab程序设计结构(Akiko is a simulation example the design of the structure of space identification algorithm in Matlab)

pfx格式或者p121格式文件的解析器， PfxTest文件 使用一个BASE64编码的P12文件字节数组，默认密码123456，CERT为三级证书，使用BC库作为JCE实现(pfx test java code , decrypt a p12 format file (such as .pfx,.p12 file) the pfxtest use a sampled p12 file which is base64 encoded, the pfx password is 123456, and is an three level cert chain, the resolve use the BC lib ——the JCE open implemention)

本代码用于模拟二维桁架结构在外载激励作用下、存在动力吸振器的情况下的响应情况，完全原创，只有一个m文件用于生成桁架振动动画的avi文件，其余三个函数用于辅助生成具体桁架结构的参数以及辅助计算。外载荷频率、动力吸振器固有频率可以通过改变代码中的变量来控制。(This code is used to simulate the two-dimensional truss structure as set out under the incentive, there are circumstances in response to the situation under dynamic vibration absorber, and completely original, only one file is used to generate m truss vibration animation avi files, the remaining three functions are used to assist generate specific parameters and supporting calculations truss structure. External load frequency, dynamic vibration absorber natural frequency can be controlled by changing the variables in the code.)

对实际降雨信道环境的模拟，根据不同的降雨概率，得到降雨的类型，以及降雨引起的路径损耗值。对于想要仿真实际环境和信道，可以加入降雨这一干扰，作为对性能评估的一个影响因素，其中涉及到的降雨类型及对应的雨衰减率依据国标。(Simulation of the actual channel environment rainfall, depending on the probability of rain, to get the type of precipitation, and the path loss value due to rainfall. For those who want the physical environment and channel emulation, you can add rain this interference as a factor for performance evaluation, which relates to the rainfall patterns and the corresponding rain attenuation rate based on the national standard.)
