The capacity of ideal MIMO channels has a high-SNR slope that equals the minimum of the number of transmit and receive antennas. This letter analyzes if this result holds when there are distortions from physical transceiver impairments. We prove analytically that such physical MIMO channels have a finite upper capacity limit, for any channel distribution and SNR. The high-SNR slope thus collapses to zero. This appears discouraging, but we prove the encouraging result that the relative capacity…

Achievable Rate of Rician Large-Scale MIMO Channels With Transceiver Hardware Impairments

It is interesting to find that the achievable rate loss depends on the Rician K- factor, which reveals that the favorable propagation in LS-MIMO systems can remove the influence of hardware impairments, and it is shown that the nonideal LS- MIMO system can still achieve high spectral efficiency due to its huge degrees of freedom.

MIMO transmission with residual transmit-RF impairments

It is demonstrated that residual distortions severely degrade the performance of (near-)optimum MIMO detection algorithms, and an efficient algorithm is proposed, which is based on an i.i.d. Gaussian model for the distortion caused by these impairments.
