中文说明：所有调制方案（如QPSK、QAM16、QAM64）的Simulink模型。这些模型用于计算误码率和误码率。利用调制方案的模型绘制了星座图和眼图。
English Description：
Simulink models for all modulation schemes like QPSK,QAM16,QAM64.These models are used to find out the bit error rate and the probability of error. the constellation diagram and eye diaram are plotted using models for the modulation schemes.
