• Large-system analysis
• massive multiple-input multiple-output (MIMO)
• time-domain vector perturbation (TDVP)

In this paper, we consider time-domain vector perturbation (TDVP) in a large-system limit when channel state information (CSI) is imperfect due to pilot contamination, and we derive the system's achievable sum rate per cell. We use random matrix methods to avoid time-consuming Monte Carlo simulations. Numerical results show that, in general, linear precoding ensures a higher sum rate than TDVP in the massive multiple-input-multiple-output (MIMO) regime.
