中文说明：资源描述 1) 分别编写BPSK与QPSK调制解调系统的Matlab仿真程序，要求： l 发送滤波器与接收滤波器均为根升余弦滚降滤波器； l 信道噪声为加性高斯白噪声 2) 绘制BPSK与QPSK调制下的误码率与信噪比曲线图，并与理论曲线进行对比
English Description：
Application background1, respectively, the preparation of BPSK and QPSK modulation and demodulation system Matlab simulation program, the requirements of:L transmit and receive filters are root raised cosine roll off filter;L channel noise is additive Gauss white noise 2) draw BPSK and QPSK modulation under the error rate and signal to noise ratio of the curve, and compared with the theoretical curve
