高通，rex，OS，很好的文档~~~！！！(Qualcomm, rex, OS, a very good document ~ ~ ~)

说明：  近两天由于研发需要OPNET这个仿真软件，同时要求可以支持wimax仿真模型，对该仿真软件的研究还需要继续进行 好不容易在网络上找到了最新版的OPNET 14.5的软件，但是安装的确出现了很大的麻烦，最后通过查阅网络上对之前版本安装的经验解决了安装过程中的问题，因此将这些分享给大家： (Almost two days because of this R &amp D needs OPNET simulation software, also required to support wimax simulation model, the simulation software is also the need to continue the network finally found the latest version of the OPNET 14.5 software, but certainly there was an installation much trouble, and finally access to the network through the installation of the experience of the previous version to solve the problems during the installation process, it will share all of these:)

该文档为一个实现ofdm子载波调制和解调的代码，利用QPSK和16QAM两种方式实现，并附有运行结果。(This document is an implementation of ofdm subcarrier modulation and demodulation of the code, the use of QPSK and 16QAM two ways, along with operating results.)

说明：  主要运用matlab仿真mpsk、16qam的星座图，里面有很多关于函数的参数注释，适合初学者(Realization of MPSK 16QAM constellation in MATLAB)

通信系统仿真原理与无线应用MATLAB仿真的源代码，内部有许多实例，让读者轻松掌握matlab(MATLAB simulation of the simulation principles of communication systems and wireless applications source code, there are many instances within, allow readers to easily grasp the matlab)

说明：  LDPC 64QAM仿真程序 matlab 有具体的编码和解码源程序，对信道编码的人很有帮助(LDPC 64QAM simulation program matlab has specific coding and decoding source program, which is very helpful to channel coding people)

说明：  2. 关于无线信道的多普勒谱，请回答以下问题： (1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请描述：自己用计算机产生的经典谱是正确的依据。(2. Regarding the doppler spectrum of the wireless channel, please answer the following questions: (1) in some wireless channels, doppler frequency shift will cause aliasing of the output signals of the wireless channel.Describe the various causes of aliasing; (2) there is a classic spectrum in the doppler spectrum in the wireless channel, please explain the mechanism of producing this spectrum shape; (3) please use Simulink tool to write code (s-function mode) to generate a single-path Rayleigh channel, whose doppler spectrum is the classical spectrum, in which the moving rate is 120km/h.And please describe: your own computer generated classical spectrum is the correct basis.)

说明：  Matlab实现多智能体一致性问题，可运行(Realization of Multi-Agent Consistency by MATLAB)
