Multi-User (MU) massive Multiple-Input-Multiple-Output (MIMO) systems are seen as one of the most promising ways to improve wireless communications. In order to prevent an excessive increase in power consumption, nonlinear one-bit precoding methods are gaining interest recently. In this work, we present a new nonlinear precoding technique, which mitigates all quantization distortions in the example of Phase-Shift-Keying (PSK). The underlying optimization problem is based on maximizing the safety margin to the decision thresholds of the receiver constellation modulation. The resulting performance gain in comparison to state-of-the-art algorithms is shown in terms of the uncoded Bit Error Ratio (BER) over the transmit power for different number of constellation points and different ratios of antennas to users. |
