From: Pilot contamination reduction in massive MIMO systems based on pilot scheduling

1: Get :β i j k , j=1,2,…,L,k=1,2,…,K,U,Φ;
2: While N U ≠0 do
3: For k=1:N U
4: Calculate ϕopt(U k ) according to (18)
5: Calculate ϕsub(U k ) according to (19)
6: Calculate d(U k ) according to (20)
7: End for
8: Calculate Usens according to (21)
9: Assign the optional pilot sequence ϕopt(Usens) to the user Usens
10: UUUsens
11: ΦΦϕopt(Usens)
12: N U N U −1
13: N Φ N Φ −1
14: End while
