用matlab实现基于网格匹配的图像拼接，其中网格大小需要自己依据图片大小进行调整(Using matlab to achieve grid-based matching of image mosaic, in which the size of the grid need to be adjusted based on image size)

本程序用于完成BPSK、QPSK、8PSK的调制仿真。并可任意扩展到MPSK和MQAM。程序分成三个部分：phase.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； model.m 为主程序，完成各种信号的基带星座图映射、脉冲成型和调制； command.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, 8PSK modulation simulation. Arbitrary and may be extended to MPSK and MQAM. Program is divided into three parts: phase.m symbol of the baseband shaping pulse sequences, optional rectangular pulse, the square root raised cosine pulse and raised cosine pulse model.m-based procedures, completed a variety of base-band signal constellation mapping , pulse shaping and modulation command.m given spectrum shows a simple test.)
