采用低通滤波法实现数字正交的matlab例程(Low-pass filtering method using digital quadrature routines in matlab)

使用matlab语言编程解决动态规划问题(Using matlab language programming to solve dynamic programming problem )

The timing_recovery_1.mdl uses Simulinks variable step solver to create a continous time QPSK signal with both carrier and symbol rate errors. This is a relativly straight forward approach, but is computationally expensive. The sescond model, timing_recovery_2Q.mdl uses a purely discrete time approach using the same fractional sample delay approach as does the receiver. This can run much faster.

本程序特别适合于弹道计算等方面使用。比ODE45函数的速度加快了很多，且程序充分展示了Matlab向量运算的强大功能，以及编程的简单快捷。(The program is especially suitable for ballistic calculation such as the use of. Than the ODE45 function more quickly, and it shows the powerful function of Matlab vector operations, and programming is simple and quick.)

这是matlab的一些程序希望对大家有用，谢谢了(This is some of the procedures of the matlab hope that useful, thank you)

直序扩频系统，首先基带信号通过脉冲成型，m序列扩频然后进行BPSK调制发送，接收端接收到信号加干扰和噪声，进行解调和解扩恢复原始信号。( The straight foreword wide frequency system, the first baseband signal through the pulse formation, the m sequence wide frequency then carries on BPSK the modulation transmission, the receive termination receives the signal to add the disturbance and the noise, carries on the demodulation and the despread restores the primary signal. )
