    Mode Switching for the Multi-Antenna Broadcast Channel Based on Delay and Channel Quantization

    Imperfect channel state information degrades the performance of multiple-input multiple-output (MIMO) communications; its effects on single-user (SU) and multiuser (MU) MIMO transmissions are quite different. ...
