Abstract: | In this paper, the performance of a proposed antenna
selection (AS) scheme for Multiple Input Multiple Output
(MIMO) networks is evaluated, where the Orthogonal Frequency
Division Multiple Access (OFDMA) physical layer protocol is
employed. The proposed AS algorithm is based on the
maximization of the ratio of desired user’s signal power to the
interference power caused to the network. Performance metrics
are derived, such as the mean number of active mobile stations
(MSs) for various modulation types and services, after a sufficient
number of Monte Carlo (MC) simulations. As results indicate, our
proposed AS approach can provide significant throughput gain
especially in cases of high data rates per active MS. In particular,
for three allocated subcarriers per MS, 16-QAM modulation type
and 10% blocking probability, this strategy provides 33% gain on
the mean number of active MSs compared to the case where
interference is neglected during antenna selection. |
