  In this work, we propose an iterative scheme for computing a linear precoder
that takes into account the impact of hardware impairments in the multiuser
multiple-input single-output downlink. We particularly focus on the case when
the transmitter is equipped with nonlinear power amplifiers. Using Bussgang's
theorem, we formulate a lower bound on the achievable sum rate in the presence
of hardware impairments, and maximize it using projected gradient ascent. We
provide numerical examples that demonstrate the efficacy of the proposed
distortion-aware scheme for precoding over a millimeter-wave~channel.
