I have a matrix A=[A0 A1]

A0 and A1 are [M x L] matrix and A is [M x LNt]

Another matrix B=[A0A0' A1A1']

B is M X M matrix and Ak' is [M x (p-L)] matrix

I have obtained A, but couldn't get B as dimensions vary

I have taken M=128,L=16,Nt=2,Nr=1,p=M/Nt=64

A is a matrix with elements A0 and A1

A=[A0 A1]

I have formed matrix A:

A0=randn(M,L);

A1=randn(M,L);

A=horzcat(A0,A1);

OK, the question becomes more concrete now. Since you have A0 and A1, then you can do

A = [A0 A1];
B = [A0*A0' A1*A1'];

What is the dimension issue you mentioned in the question?
