Reduced Dimension Minimum BER PSK Precoding for Constrained Transmit Signals in Massive MIMO

ICASSP 2018accepted

Recently a number of nonlinear precoding algorithms have been developed for designing a downlink transmit signal that is constrained by some nonlinearity, such as one-bit quantization, power-amplifier saturation or constant modulus. These methods use iterative search algorithms to directly design th…

Minimum probability-of-error perturbation precoding for the one-bit massive MIMO downlink

ICASSP 2017accepted

Linear precoders have been shown to perform reasonably well at low SNR when the basestation of a MIMO downlink employs one-bit digital-to-analog converters to quantize the precoder outputs. However, at medium-to-high SNRs, an error floor is encountered due to the coarse quantization. This paper exam…
