matlab实现矩形脉冲和根升余弦脉冲的QPSK调制功率谱密度及不同信噪比信道下的星座图，直接运行main函数即可(Plot the power density spectrum of the transmitted signal (e.g., with the matlab function psd) with different pulse shapes. How is it affected if a root raised cosine pulse is chosen instead of a rectangular pulse shape? Study the signal constellation in the receiver for various values of Eb/N0 for the AWGN channel. )

产生噪声函数矩阵，噪声的大小可以根据参数改变。最后可以给图像加噪声(Noise function)
