M=2;
N=64;
Np=4;
Nframes=1000;
D = round((M-1)*rand((N-Np),Nframes));
Mod=pskmod(D,M);
Mod=Mod';
pilot=3+3j;
pilotdata=zeros(1000,64);
% p=1:1000;
u=0;
% k=1;
for p=1:1000
for q=1:13:52
pilotdata(p,q)=pilot;
for J=q+1:q+12
k=q-u:q-u+11;
pilotdata(p,J)=Mod(p,k);
u=u+1;
end
end
end
n=49;
for m=(53:64)
pilotdata(p,m)=Mod(p,n);
n=n+1;
end

You have a problem of dimensions at line 18:
pilotdata(p,J)=Mod(p,k);
At the first iteration, it holds: p = 1, q = 1, J = 2
pilotdata(1,2) is a scalar value (dimension 1 x 1) but k = 1 : 12
Mod(p,k) is a vector of dimension 1 x 12
You cannot assign this value to a scalar value.
What was your objective here ?
