AVS PART2的参考代码，最新版本rm52j。(AVS PART2 reference code, the latest version of rm52j.)

首先产生两个独立的随机过程，并将它们用正交载波进行调整得到带通随机过程的抽样(First generate two independent random process, and to adjust them by using orthogonal carrier band-pass random process of sampling)

说明：  扩频程序，毕业设计时编写的，很好用。MATLAB程序，可以直接调用(Spread spectrum program, written when graduation project, very easy to use)

说明：  本文阐述了扩展频谱通信技术的理论基础和实现方法，利用MATLAB 提供的可视化 工具Simulink 建立了扩频通信系统仿真模型，详细讲述了各模块的设计，并指出了仿真建模 中要注意的问题。在给定仿真条件下，运行了仿真程序，得到了预期的仿真结果。同时，利 用建立的仿真系统，研究了扩频增益与输出端信噪比的关系，结果表明，在相同误码率下， 增大扩频增益，可以提高系统输出端的信噪比，从而提高通信系统的抗干扰能力。 (This paper describes the theory of spread-spectrum communication technology and implementation methods based on the use of visualization tools provided by MATLAB Simulink to establish a spread spectrum communication system simulation model, described in detail the design of each module, and pointed out that the simulation modeling to note problem. In the given simulation conditions, running a simulation program to obtain the desired simulation results. Meanwhile, the use of the simulation system to study the spreading gain and the relationship between the output signal to noise ratio, results show that the same bit error rate, increased spreading gain can increase the system output signal to noise ratio, thereby enhancing communication system disturbance.)

各种混沌吸引子的演示程序，很经典，也很好用。(A variety of chaotic attractor of the demo program, it is classic, but also a very good use.)

说明：  fft代码,采用蝶形算法,包括C,matlab和verilog代码(fft code, using butterfly algorithm, including C, matlab and Verilog code)

that is Matlab code for GLM and LASSO, enjoy it!

基于紧格式线性化方法与偏格式线性化方法，可将非线性系统线性化，后用PID控制，设计控制器(Based on tight format linearization method and partial format linearization method, nonlinear system can be linear, with PID control, to design the controller )
