Here is my code
clear all;
close all;
n=5;
b=[1 0 0 1 0];
fc=8000;
Rb=1000;
t=1/Rb;
xu = waveplot(b,'unipolar_nrz');
fs = 1/t;
ts = 1/fs:1/fs:1;
xs = cos(2*pi*fc*ts);
sa = mixer( xu, xs );
subplot(211), waveplot(xu)
subplot(212), waveplot(sa)
figure
interval [ 0, 20 kHz ].
fr = [ 0, 20000 ];
subplot(211), psd(xu,fr)
subplot(212), psd(sa,fr)

xu = wave_gen(b,'unipolar_nrz'); % here is the main issue
fs = 1/t;
ts = 1/fs:1/fs:1;
xs = cos(2*pi*fc*ts);
sa = mixer( xu, xs );
subplot(211), waveplot(xu)
subplot(212), waveplot(sa)
figure
