| Resumo | |
The use of low-resolution quantization is a promising approach to reduce the power consumption of the analog-to-digital converters (ADCs) of future wireless communications systems. In this work, we investigate a multi-user MIMO downlink scenario with 1-bit quantization and temporal oversampling at the receivers. The information is encoded in the zero-crossings (ZXs) in such systems, a concept which is known as zero-crossing modulation (ZXM). ZXM could enable energy-efficient communications in the internet of things (IoT) or wideband systems operating on millimeter-wave and terahertz bands. Here, we compare two practical ZXM waveform mappings in terms of their uncoded bit error rate and evaluate a lower bound on their spectral efficiency when employing minimum mean squared error (MMSE) precoding.
