Coordinated transmission between base stations is one of the techniques under investigation to further improve the system performance of E-UTRA. In general, such a coordination, sometimes also called network MIMO, requires a large amount of signaling between cells. A relatively simple scheme for cell coordination is macro diversity. In this paper we consider macro diversity for the downlink direction...
The optimal tradeoff between diversity gain and multiplexing gain for multiple-input multiple-output (MIMO) channels has been studied recently under the independently identically distributed (i.i.d) Rayleigh fading assumption. In this paper, we extend the results and derive the optimal tradeoff performance for a general fading channel setup with generic probability density functions for channel coefficients,...
