We consider the impact of transmitter correlation and mutual coupling on MIMO MRC systems. We present optimal transmission strategies for three input power metrics as well as formulas for the resulting outage probabilities. Numerical results suggest that, regardless of the power metric, most of the performance benefits of MIMO MRC can be obtained with transmit antennas spaced as close as 0.2 - 0.3 wavelengths.
