QAMXIANGP
本程序仿真了16QAM信号的载波相偏估计的HOS算法，整个算法实现分为（1）模拟发送端发送16QAM信号；（2）加入相偏来模拟通过信道后有相偏的测试信号；（3）利用HOS算法进行相偏估计与纠正；（4）输出星座图。(This procedure simulated a 16QAM signal carrier phase offset estimate of the HOS algorithm, the algorithm is divided into (1) analog transmitter to send 16QAM signal (2) by the inclusion of partial to simulate the channel after the phase offset of the test signal (3 ) algorithm using HOS phase offset estimate and correction (4) output constellation.)

说明： 基于MATLAB的“电力电子技术"仿真实验的研究
为了方便地对这些变流电路进行仿真，
采用了MATLAB的Simulink库。同时，还采用VISUAL BASIC语言将电力电子变流电路的波形与MATLAB
仿真界面进行链接，以便更简洁地、直观地，甚至是在无人指导的情况下，让学习者独立地完成电力电子
变流电路的仿真实验。
(MATLAB based on the " Power Electronics" simulation study in order to facilitate these changes to circuit simulation using the MATLAB-Simulink library. At the same time, the use of VISUAL BASIC language of power electronic converter circuits and the MATLAB simulation waveforms link interface for a more concise and intuitive manner, even in the absence of guidance to enable learners to complete the independent power electronic converter circuit simulation.)
