QPSK.rar
- QPSK是一种二维调制技术,其中水平轴称为同相轴,垂直轴称为正交轴,分别对应于星座图上的1和Q坐标。同相载波指载波本身,正交载波指相位旋转90度的载波1周。QPSK调制在实现时是采用正交调幅的方式,某星座点在1坐标上的投影去调制同相载波的幅度,在Q坐标上的投影去调制正交载波的幅度,然后将两个调幅信号相加就是所需的调相信号,QPSK is one kind of two-dimensional modulating technology, the horizontal axis is called

modulation
- 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, 16QAM, 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 (N为星座图的点数)所对应的星座坐标;再将输入的二进制序列转化为相应的十进制,以查表的方法查出对应点的复数坐标,即为调制映射后的结果。-this program is used for BPSK,QPSK,16QAM and 64QAM modulation
