User Activity Detection with Delay-Calibration for Asynchronous Massive Random Access
Zhichao Shao, Xiaojun Yuan, Rodrigo C. de Lamare +1
This work considers an uplink asynchronous massive random access scenario in which a large number of users asynchronously access a base station equipped with multiple receive anten…
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…
Study of Channel Estimation with Oversampling for 1-bit Large-Scale MIMO Systems
Z. Shao, L. Landau, R. de Lamare
In this paper, we propose an oversampling based low-resolution aware least squares channel estimator for large-scale multiple-antenna systems with 1-bit analog-to-digital converter…
