Spatial Data Multiplexing Over OFDM/OQAM Modulations

Multi-carrier modulations (MCM) and especially orthogonal schemes such as orthogonal frequency division multiplexing (OFDM) are currently used in many radio transmission standards. Among these modulations, OFDM/OQAM (also referred as OFDM/Offset QAM) is an interesting alternative to classical OFDM modulation, as it does not require the use of guard interval. This characteristic makes its spectral efficiency optimal. In this paper we investigate the combination of OFDM/OQAM and multiple-input multiple-output (MIMO) over radio channels associated to non iterative and iterative receivers. We focus on spatial data multiplexing (SDM) which is a well known MIMO technique designed to improve the capacity.
