  Multiple-input multiple-output orthogonal frequency division multiplexing
with index modulation (MIMO-OFDM-IM) is a novel multicarrier transmission
technique which has been proposed recently as an alternative to classical
MIMO-OFDM. In this scheme, OFDM with index modulation (OFDM-IM) concept is
combined with MIMO transmission to take advantage of the benefits of these two
techniques. In this paper, we shed light on the implementation and error
performance analysis of the MIMO-OFDM-IM scheme for next generation 5G wireless
networks. Maximum likelihood (ML), near-ML, simple minimum mean square error
(MMSE) and ordered successive interference cancellation (OSIC) based MMSE
detectors of MIMO-OFDM-IM are proposed and their theoretical performance is
investigated. It has been shown via extensive computer simulations that
MIMO-OFDM-IM scheme provides an interesting trade-off between error performance
and spectral efficiency as well as it achieves considerably better error
performance than classical MIMO-OFDM using different type detectors and under
realistic conditions.
