N2 - The combination of coarse quantization with Constant Envelope (CE) signaling at the transmitter is of paramount importance in massive Multiple-Input Multiple-Output (MIMO) systems due to its power efficiency. In this context, we present a nonlinear precoder design for single-carrier transmission with frequency-selective channels. The optimization problem is formulated for Quadrature Amplitude Modulation (QAM) signaling as a linear programming problem. Simulation results show significant gains compared to the linear precoders.
