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

对光信号的脉冲宽度调制，采取c语言和汇编语言结合起来提高准确率，两种语言都有其优越性。-Light pulse width modulation signals, to take c language and assembly language to improve the accuracy of combining the two languages has its advantages.
