Abstract :
This work analyzes the impact of radio frequency transmitter impairments on the performance of Multiple-Input Multiple-Output (MIMO) systems with nonlinear Tomlinson-Harashima and vector precoding. This analysis is carried out by means of simulation results using two sorts of scenarios: spatially-white Rayleigh channels and measured indoor channels. We also show that incorporating the transmitter noise in the precoder design produces a significant performance improvement.
