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…

Prediction of MIMO Channel Distribution with Transceiver Antenna Limitations

It is proved analytically that such physical MIMO/SISO channels have a finite upper capacity limit, for any channel distribution and SNR, and it is proved that the relative capacity gain of employing MIMo/S ISO is at least as large as with ideal transceivers.

Impact of transceiver hardware impairments on the ergodic channel capacity for Rayleigh-product MIMO channels

By considering the residual hardware transceiver hardware impairments into account, the ergodic channel capacity of a MIMO system with optimal receivers in the case of insufficient scattering is derived and it is observed that the higher the “richness” of the scattering environment, the higherThe ergodIC channel capacity till it gets saturated.

Performance analysis of MIMO-OFDM system with transceiver hardware impairments

The MIMO-OFDM model is analysed in which the Capacity and Finite SNR multiplexing gain is compared by varying the SNR and number of antennas with or without considering the hardware impairments i.e. quantization noise, non-linearties of amplifiers, I-Q imbalance and phase noise etc.

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.
