16QAM调制与解调的MATLAB实现及调制性能分析(MATLAB realization of 16QAM modulation and demodulation and modulation performance analysis)

单模型与多模型下的pdaf算法，值得下载。(Single model and multiple models under the pdaf of algorithm, it is worth the download.)

课程设计做的车牌识别，运行licence_recognise.m选择实例图片，按空格单步，直到最后识别(Curriculum design license plate recognition, run licence_recognise.m select instances pictures, press the space single step, until the final identification)

该m文件为克里金插值程序，m文件里面附上了英文注释及例子。(The m file Kriging m file inside enclosed English notes and examples.)

使用此函数来提取一个地理坐标输入字符串了。该功能非常灵活，因此，协调可能位于任何地方的字符串，并可能有许多的格式之一。(Use this function to extract one geographical coordinate out of an input string. The function is extremely flexible, thus the coordinate may be located anywhere in the string and may have one of many formats.)
