MU-MIMO Downlink Capacity Analysis and Optimum Code Weight Vector Design for 5G Big Data Massive Antenna Millimeter Wave Communication

Algorithm 1

Steps for the proposed power iteration method.

Step 1: Initial Inputs. number of users ;

number of iteration ;

initial non-zero vector ;

Tolerance .

Step 2: For  : //to construct the CICTM for each user;

Calculate and as defined in Section 2.2;

Calculate for as in (7);

Construct the CICTM for each user as in (29);

End

Step 3: For : //to compute for each user.

Calculate matrix for th user as in (31)

Step 4: While  ;

set: , and ; (normalisation)

“the value of is the scaled version of ”

if , then ;

else, set ;

end

Step 5: calculate the dominant eigenvector ;

the dominant eigenvalue ;

End;

Step 6: SLNR maximise weight vector ;

End;

Step 7: Output: the optimum weight vector for each user.
