本程序是QAM的调制程序，以及我在编程时测试用的例子，还有空时分组码中的线性分散码进行处理时所需要的向量化函数VEC还有它的逆函数，希望对大家有帮助-This procedure is the QAM modulation procedures, as well as when I test in the programming examples, as well as space-time block codes in a linear dispersion code when needed to quantify the function of VEC also its inverse function, in the hope that We have to help
