A simple algorithm to select user-pair and allocate frequency
band is proposed for multiuser-MIMO OFDMA systems. For
sake of comparison, various resource allocation algorithms,
such as max-throughput, best-fit, first-fit, and random-fit algorithm,
are examined with regard to the system throughput, computational
complexity, and fairness among the users. Computer
simulation results show that the first-fit algorithm can achieve a
large reduction of computation for resource allocation as well
as good fairness among users, with only a small reduction of
throughput.
