Hello,
I have a block of N binary phase shift keying (BPSK) symbols, each symbol with time Ts. How can I convert this block into continuous time domain? Is the following segment correct:
if true
t= 1:Ts:N*Ts;
x=2.*(randn(1,N)>0.5)-1;
xt=interp1(t,xCP,t,'linear');
end
Thanks

It is hard to guess. You create "x", but use "xCP". You interpolate the values of xCP at the points "t", while the original values are available at the same points "t". Therefore the interpolation is equivalent to:
xt = xCP;
Is this your intention?
