Abstract :
In this paper, we consider multiuser space-time block codes (STBCs) for 2times2 multiple-input multiple-output (MIMO) uplink transmissions. Using a truncated union-bound (UB) approximation, we propose design criteria of multiuser STBCs for quasi-static fading MIMO multiple access channels (MACs). Next, we demonstrate how, by combining the structure of algebraic perfect STBCs in [10], a family of multiuser STBCs can be constructed to fulfill the design criteria, and show that the proposed STBC outperforms all previously known codes over quasi-static fading MIMO MACs.
