This paper provides general and deep investigation of adaptation strategies based on the channel inversion policy regarding wide variety of channel modes. Our novel approach to the eigenmode space MIMO channel inversion policy relies on the eigenmode space reduction providing zero transmission outage probability regardless of the instantaneous channel fading realization. Very detailed survey of the features of channel capacity is provided in analytical closed form expressions supported by many particular numerical results (Alamouti scheme is included). The correlated MIMO channel is involved into our treatment as well. We also address the trade-off between the capacity and transmission outage probability. The novel results are developed in the general framework with exhaustive summary of well known SISO and SIMO results.
