In this paper we consider the vector perturbation (VP) precoding scheme for the multiuser MISO broadcast channel proposed by Hochwald et al. under the practical assumption that the receivers have limited dynamic range. In this case, VP precoding is shown to suffer from an error floor at high signal-to-noise ratio (SNR). As an alternative, we propose precoding with restricted VP (RVP), which takes...
Many studies investigate wireless communication systems with multiple antennas on both sides of the link (MIMO systems) for future high-speed mobile communications. With these systems, the spatial properties of the propagation channel can be exploited. This paper deals with the investigation of MIMO systems on system level for the downlink case. In this scenario multiuser interference affects the...
