BPSK和QPSK的调制程序，完全按照通信原理书上的步骤做的，仿真结果正确(BPSK_QPSK_Modulation)

说明：  BP算法客运量预测，十分详细的好资料，值得参考(Passenger Volume Forecast BP algorithm, a very good detailed information, it is also useful)

这个matlab程序通过Galerkin方法求解常微分方程组，当然求解的结果是Differential Equations (ODE)近似的解。(Differential Equations (ODE) Solver through Galerkin Method)

说明：  实现了系统辨识的算法，Matlab实现了产生一均值为0，方差为1的噪声，给出系统辨识的效果。(To achieve the system identification algorithm, Matlab realized generated a mean 0 and variance of a noise, the effect of system identification is given.)
