实现了QPSK在瑞利信道下的性能仿真,仿真结果与理论曲线相比较，结果相符。供大家参考。(It achieved the simulation of QPSK performance in Rayleigh channel.)

说明：  只需输入车辆图片，即可实现包括车牌检测、车牌定位、车牌字符分割、车牌字符识别的全流程图形化演示，非常形象！拥有完整matlab源代码，是学习模式识别的高贵编程参考。(Just enter the vehicle picture, you can achieve, including license plate detection, license plate location, license plate character segmentation, the whole process of license plate character recognition graphical presentations, very image! Matlab has a complete source code, is to learn the noble pattern recognition programming reference.)
