In this simulink model , QPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.

说明：  坐标转换：已知n个点在a,b两坐标系中的坐标值，采用优化方法求转换关系（标准的7参数转换关系，x,y,z的移动，x,y,z的旋转，以及缩放系数）ps:附带空间旋转公式。input: points in A and B。 output：transfer relationship （u,v,w: shit of x,y,z。 a,b,g: rotate of x,y,z 。k：zoom）(Coordinate Transfer:A,B are tow coordinates. This program using optimal method to find the transfer relationship of A and B. input: points in A and B。 output：transfer relationship （u,v,w: shit of x,y,z。 a,b,g: rotate of x,y,z 。k：zoom） )
