OFDM/OQAM modulation scheme is an alternative to the conventional cyclic-prefix OFDM (CP-OFDM) modulation. It allows a larger theoretical spectral efficiency as it does not require the use of any guard interval. In this paper we investigate and evaluate channel estimation for OFDM/OQAM modulations in multiple-input multiple-output (MIMO) context. We focus on transmission over radio channels and use a two transmit antenna spatial data multiplexing (SDM) scheme. Direct and iterative channel estimation algorithms are evaluated and compared in this paper.
