TLDR
The optimal tradeoff between diversity gain and multiplexing gain for multiple-inputmultiple-output (MIMO) channels has been studied recently and the optimal tradeoffs are derived for generalized fading channel conditions, including different fading types, nonidentical fading distributions, spatial correlation, and nonzero channel means.Abstract:
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, which includes many known models as special cases. The effects of non-identical distribution, correlation and non-zero channel means are also treated.read more
