利用一数学仿真工具构建一16-QAM的通信系统 工具：推荐使用Matlab,可使用信号处理工具箱但不能利用通信工具箱(The use of a mathematical simulation tools to build a 16-QAM communication system tools: Recommended use of Matlab, Signal Processing Toolbox can be used but not the use of communication toolbox)

对川渝电网中太白火电机组进行的simulink仿真，励磁等发电机控制部分采用实际的参数，此仿真为单机无穷大系统。(Simulink simulation of the Sichuan Chongqing power grid in Taibai thermal power unit, excitation generator parameters using the actual control, the simulation for single machine infinite bus system.)

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.
