This paper proposes a novel bandwidth-efficient multiuser scheme with multiple antennas. By assigning each user a two-dimensional signature matrix and user-specific interleaver, K users can can occupy the same bandwidth as the single user. Both theoretical analysis and simulation results show that the single-user like performance can be achieved asymptotically.
