8QAM
利用Matlab仿真软件,完成如图1所示的一个基本的数字通信系统。信号源产生0、1等概分布的随机信号,映射到16QAM的星座图上,同时一路信号已经被分成了实部和虚部,后边的处理建立在这两路信号的基础上。实部、虚部信号分别经过平方根升余弦滤波器,再加入高斯白噪声,然后通过匹配滤波器(平方根升余弦滤波器)。最后经过采样,判决,得到0、1信号,同原信号进行比较,给出16QAM数字系统的误码。(Using Matlab simulation software, as shown in Figure 1 to complete a basic digital communications systems. Signal source such as arise over the distribution of 0,1 random signal, is mapped to 16QAM constellation diagram, at the same time all the way the signal has been divided into real and imaginary parts, behind the deal with the establishment of these two signals in the basis. Real part, imaginary part of the signal, respectively, after a square root raised cosine filter, then add white Gaussian noise, and then through the matched filter (square root raised cosine filter). Finally, after sampling, the verdict has been 0,1 signal, to compare with the original signal is given 16QAM digital system error.)
