Multiuser-MIMO Systems Using Comparator Network-Aided Receivers With 1-Bit Quantization
Ana Beatriz L. B. Fernandes, Zhichao Shao, Lukas T. N. Landau +1
Low-resolution analog-to-digital converters (ADCs) are promising for reducing energy consumption and costs of multiuser multiple-input multiple-output (MIMO) systems with many ante…
Minimum Symbol Error Probability Low-Resolution Precoding for MU-MIMO Systems With PSK Modulation
Erico S. P. Lopes, Lukas T. N. Landau, Amine Mezghani
We propose an optimal low-resolution precoding technique that minimizes the symbol error probability of the users. Unlike existing approaches that rely on QPSK modulation, for the…
Discrete MMSE Precoding for Multiuser MIMO Systems with PSK Modulation
Erico S. P. Lopes, Lukas T. N. Landau
We propose an optimal MMSE precoding technique using quantized signals with constant envelope. Unlike the existing MMSE design that relies on 1-bit resolution, the proposed approac…
Dynamic Oversampling Tecniques for 1-Bit ADCs in Large-Scale MIMO Systems
Z. Shao, L. Landau, R. de Lamare
In this work, we investigate dynamic oversampling techniques for large-scale multiple-antenna systems equipped with low-cost and low-power 1-bit analog-to-digital converters at the…
Joint AGC and Receiver Design for Large-Scale MU-MIMO Systems Using Low-Resolution Signal Processing in C-RANs
T. Cunha, R. C. de Lamare, T. N. Ferreira +1
Large-scale multi-user multiple-input multiple-output (MU-MIMO) systems and cloud radio access networks (C-RANs) are considered promising technologies for the fifth generation (5G)…
Study of Channel Estimation Algorithms for Large-Scale Multiple-Antenna Systems using 1-Bit ADCs and Oversampling
Z. Shao, L. Landau, R. C. de Lamare
Large-scale multiple-antenna systems with large bandwidth are fundamental for future wireless communications, where the base station employs a large antenna array. In this scenario…
