This paper analyzes the impact of transmitter noise on the performance of Multiple-Input Multiple-Output (MIMO) systems with linear and nonlinear receivers and precoders. The authors show that the performance of MIMO linear and decision-feedback receivers is not significantly influenced by the presence of transmitter noise, which does not hold true in the case of MIMO systems with precoding. Nevertheless, the authors also show that this degradation can be greatly alleviated when the transmitter noise is considered in the MIMO precoder design.
