Multiuser MIMO Transmission with Limited Feedback, Cooperation, and Coordination

  1. Content type: Research Article

    It is well known that multiple-input multiple-output (MIMO) techniques can bring numerous benefits, such as higher spectral efficiency, to point-to-point wireless links. More recently, there has been interest ...
