Matlab code for VaR

无码间串扰传输条件，程序段经过仿真后所呈现的图形非常完美，大家可以试试看。(No intersymbol crosstalk transmission conditions, procedures, after the segment through the simulation of the graphics rendering is perfect, we can give it a try.)

说明：  这是一个混沌理论中重要的Logistic映射的程序。通过曲线很容易看到奇妙的混沌现象(This is a chaos theory important Logistic mapping procedures. Through curve is easy to see the amazing phenomenon of Chaos)

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.
