Algorithm 1 AP set decision algorithm for maximizing the performance diversity combining

1:
$input : [a_{1}, a_{2}, \dots, a_{N_{s}}]$
2:
$filter APs with a value lower than the threshold SINR as follows :$
3:
$[a_{1}, a_{2}, \dots, a_{N_{s}}] \to [a_{1}, a_{2}, \dots, a_{N_{s}^{*}}]$
4:
$sort the filtered APs in descending order based on the SINR value$
5:
$initialize parameters; A_{1} \leftarrow [a_{1}], A_{2} \leftarrow [a_{1}, a_{2}], i \leftarrow 2, and calculate P_{s} (A_{1})$
6:
while $i \leq N_{s}^{*}$ do
7:
$calculate P_{s} (A_{2})$
8:
if $P_{s} (A_{1}) < P_{s} (A_{2})$ then
9:
$A_{1} \leftarrow A_{2}$
10:
$A_{2} \leftarrow [a_{1}, a_{2}, \dots, a_{i + 1}]$
11:
$i \leftarrow i + 1$
12:
else
13:
$A^{*} \leftarrow A_{1}$
14:
end if
15:
end while
16:
$output : A^{*}$
