MPSKTransmissonwithGausNoise
- 本程序用于完成BPSK、QPSK、8PSK的调制仿真。并可任意扩展到MPSK和MQAM。程序分成三个部分:phase.m对基带码元序列进行脉冲成型,可选矩形脉冲,升余弦脉冲和平方根升余弦脉冲; model.m 为主程序,完成各种信号的基带星座图映射、脉冲成型和调制; command.m给出一个简单的频谱显示测试。-This procedure for the completion of BPSK, QPSK, 8PSK modulati
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 modul
demodulation
- 由信道信号的复数值找出对应的二进制序列。方法如下:由信道值,求出该值与星座图中所有点的距离,找出距离最小的点,该点对应的二进制序列及为该信道对应的解调结果。-this program is used for BPSK,QPSK,16QAM and 64QAM demodulation.
QPSK
- 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,
