Algebraic Multiuser Space–Time Block Codes for a 2 $\times$ 2 MIMO

Yi Hong, E. Viterbo
2009 IEEE Transactions on Vehicular Technology  
We focus on multiuser space-time block codes (STBCs) for a 2 × 2 multiple-input-multiple-output (MIMO) uplink transmission. Based on full-diversity algebraic rotations, we propose a family of multiuser STBCs constructed to minimize a truncated union-bound (UB) approximation. The proposed codes do not incur in any peak-to-average penalty and outperform all previously known multiuser STBCs. Index Terms-Full-diversity algebraic rotation, multiple-input multiple-output (MIMO), multiuser.
