这是一个关于完成QAM调制的Matlab示例程序(This is a complete QAM modulation on the sample of Matlab procedures)

参考Matlab提供的模块建立简化的三相锁相环的仿真模型，只保留必要的步骤，如abc-dqz只计算Vq，去除频率反馈模块和自动参数调整模块等。 建立单相锁相环的计算模型  简化单相锁相环的系统结构，保留必要的PI控制器等模块  验证并讨论输入信号频率在45-65Hz变化时设计的锁相环的动静态性能  仿真并分析三相输入信号包含谐波、不平衡和直流偏移时锁相环的锁相结果(Reference Matlab provides three-phase PLL module to establish a simplified simulation model, retaining only the necessary steps, such as abc-dqz counting only Vq, remove frequency feedback module and automatic parameter adjustment module.  simulation and analysis of the three-phase input signal contains harmonics, unbalance and DC offset PLL phase-locked Results)

本程序的功能是用支路追加法求阻抗矩阵,再用三相短路计算短路电流和电压(The function of this procedure is to use branch supplementary method for impedance matrix, with a three phase short circuit calculation of short circuit current and voltage)

this is a good book to learn the matlab. from here , you can learn a lot idea about write the matlab code.
