说明：  根据输入的调制方式，对输入序列MOD_IN进行调制，分别采用BPSK, QPSK, !6QAM, 64QAM，完成对星座图的映射，输出为Y.转化的方法为：先写出十进制情况下从0 到N-1
(According to the modulation input of the input sequence MOD_IN modulation, respectively, using BPSK, QPSK,! 6QAM, 64QAM, completion of the mapping constellation diagram, the output for Y. transformation method as follows: first write a decimal from 0 to N-1)
