十二星座日期是不是改了

物理层网络编码仿真MPSK如何星座映射的？用matlab实现...下面的点如何映射到上面的点？？？求指导。。。

如果是基带信号可以直接scatterplot就可以了，a=randi(2,A=pskmod(a,A=awgn(A,

matlab 怎么改变8QAM的星座映射方式

% Random symbols% Use 16-QAM modulation.hMod = modem.qammod(M);% Create a scatter plot and show constellationscatterPlot = commscope.ScatterPlot('Constellation'x);% Transmit signal through an AWGN channel.ynoisy = awgn(y;'measured',% Create scatter plot from noisy data.update(scatterPlot;% Demodulate ynoisy to recover the message.z=demodulate(hDemod;% Check symbol error rate.[num;rt] = symerr(x,z)The output and scatter plot follow. Your numerical results andplot might vary;because the example uses random numbers.num = 83rt = 0.0166,
