Abstract:	This paper focuses on soft-output detection when coded spatial data multiplexing schemes are combined with filter bank multicarrier systems based on the offset quadrature amplitude modulation (FBMC/OQAM). Due to the modulationinduced interference, which is inherent to FBMC/OQAM, the soft-output detection is not trivial. The proposed technique circumvents this problem by removing the interference with reduced complexity. The complexity of the proposed receiver and the system performance are evaluated and compared with the equivalent OFDM one. When the receiver has more antennas than the transmitter, both schemes give similar performance thus, supporting FBMC/OQAM, which presents less complexity.
