用MATLAB语言编写的智能计算曲线衰减率，上升时间，稳定时间，过度时间，振荡周期，峰值等。简单实用。-Using MATLAB intelligent computing curve decay rate, rise time, settling time, over time, the oscillation period, peak and so on. Simple and practical.

QPSK调制后产生QPSK信号，QPSK信号分别通过AWGN信道、Rayleigh衰减信道和Rician衰减信道，分别通过QPSK解调出数字信号，通过输入与输出数字信号的对比计算出仿真过程中的传输误比率，并将其与各衰减信道的理论误比率进行对比-Generate QPSK signal QPSK modulation, QPSK signals through AWGN channel, Rayleigh fading channel and Rician fading channel, resp
