User pairing method of MU-MIMO based on SLNR

The invention discloses a user pairing method of MU-MIMO based on SLNR. Steps for determining paired users comprise: calculating a first SLNR value of the current unpaired user in an index collection A2 of the unpaired users; calculating a second SLNR value generated when the each paired user in the...

Zusammenfassung:	The invention discloses a user pairing method of MU-MIMO based on SLNR. Steps for determining paired users comprise: calculating a first SLNR value of the current unpaired user in an index collection A2 of the unpaired users; calculating a second SLNR value generated when the each paired user in the index collection A1 of the paired users pairs with the current unpaired user in the A2; calculating a product of the first SLNR value of the current unpaired user and the second SLNR value of the each paired user in the A1 and taking the product as the SLNR value of the current unpaired user; calculating the SLNR value of the each unpaired user in the A2 and taking the user with the largest SLNR value as the new paired user. By using the method of the invention, system performance can be raised.
