T = 1/Fs; % 采样周期(s)

S = load('16PSK数据.TXT', 'ascii');
Len = numel(S(:, 2)); % 数据长度,点的个数
t = (0:Len-1)*T;
SAve = mean(S(:, 2)); % 求出采样数据均值
N = length (t);
df = Fs /N; %分辨率
%---------------------------------------------------
SAve0 = S(:, 2) - SAve; % 0均值
SAveVer = SAve0'; % 求矩阵SAve0的转置

SINWave = 103*sin(2*pi*Fc*t+20*pi/16);
COSWave = 103*cos(2*pi*Fc*t+20*pi/16);

IOUT = (SAveVer.*SINWave)/40+800;
QOUT = (SAveVer.*COSWave)/40+2000;
现在最后一步已经求出正交支路数据、同相支路数据IOUT、QOUT,为了画出眼图,请问下接下来该怎么做?网上说的要把数据通过滚降滤波器,是把两路数据分别通过吗?请大家帮帮忙,谢谢了
很厉害的样子
