Abstract: In recent years, a multi-antenna system is actively used
to improve the performance of the communication. A MIMO-OFDM
system can provide multiplexing gain or diversity gain. These gains
are obtained in proportion to the increase of the number of antennas.
In order to provide the optimal gain of the MIMO-OFDM system,
various transmission and reception schemes are presented. This paper
aims to propose a hybrid scheme that base station provides both
diversity gain and multiplexing gain at the same time.
