Diversity and Multiplexing Tradeoff in General Fading Channels

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.
