Double single-carrier space frequency block coding for SC-FDMA MU-MIMO: Performance evaluation

Previous studies already introduced Single Carrier Space Frequency Block Coding (SC-SFBC), a robust and flexible Alamouti-based transmit diversity technique compatible with Single Carrier Frequency Division Multiple Access (SC-FDMA). SC-SFBC was proposed, optimized and evaluated for single-user (SU)-Multiple-Input Multiple-Output (MIMO) configurations. In this paper, we investigate specific techniques of parameter optimization for multi-user (MU)-MIMO SC-SFBC, taking into account performance and complexity considerations.
