On the Capacity Gain From Antenna Correlation in Multi-User MIMO Systems

In this paper, the authors consider multi-user Multiple-Input Multiple-Output (MIMO) systems over either Multiple Access Channels (MACs) or Broadcast Channels (BCs). Contrary to common views, they show that antenna correlation at the Mobile Unit (MU), the Base Station (BS) or both sides can be potentially beneficial for such systems. Both asymptotic analysis and numerical results indicate that antenna correlation can provide a significant capacity gain in multi-user environments. A Multiple-Input Multiple-Output (MIMO) system employs multiple antennas at both the transmitter and receiver sides to enhance the performance of wireless communication.
