中文说明：主要用来仿真QAM的关于MATLAB的调制和解调代码，重点仿真了在高斯白噪声下的性能分析，同时画出了各个数据处理节点的波形图，重点画出了星座图，误码率等指标性能。后期会重点讲相关的matlab代码移植到FPGA中进行设计实现。
English Description：
Mainly used to simulate QAM about matlab modulation and demodulation code, focusing on the simulation of the performance analysis in Gaussian white noise, while drawing the waveform of each data processing node, focusing on the constellation, bit error rate and other indicators of performance. Later will focus on the relevant matlab code transplantation to FPGA design and implementation.
