Abstract A Block-Level Space-Time Block Code (BL-STBC) is firstly proposed for Multi-User Multiple-Input Multiple-Output Single-Carrier Frequency Division Multiple Access (MU-MIMO SC-FDMA) systems. Next, employing the algebraic properties of the BL-STBC and a particular permutation matrix, a low-complexity algorithm is derived for the multi-user detector. Finally, the average bit error rate is given via simulation. The performance of the BL-STBC is better than the space-frequency block code, with no added complexity, if the distributed sub-carrier mapping is used.
