Several new multi-carrier transmission techniques such as Filter Bank Multi-Carrier (FBMC), Universal Filtered Multi-Carrier (UFMC), and Generalized Frequency Division Multiplexing (GFDM) are being proposed as alternatives to orthogonal frequency division multiplexing (OFDM) for future wireless communication systems. Since multiple-input multiple-output (MIMO) will be an integral part of the 5th Generation (5G) cellular systems, the performance of these new schemes needs to be investigated for MIMO system. Space-time block codes (STBC) are widely used in MIMO system because of their ability to achieve full diversity and the simple linear processing at the receiver. In this work, we propose different approaches for the application of STBCs in UFMC. These approaches are based on type of receive filtering used for UFMC. Moreover, we also investigate the performance of these proposed schemes over frequency selective environments, and compare it with the performance of the other non-orthogonal techniques mentioned above.
