Dynamic Oversampling in 1-Bit Quantized Asynchronous Large-Scale Multiple-Antenna Systems for Sustainable Iot Networks

Zhichao Shao, Lukas T. N. Landau, Rodrigo C. de Lamare

ICASSP 2020accepted

In this paper, we propose a dynamic oversampling technique for asynchronous large-scale multiple-antenna systems with 1-bit analog-to-digital converters at the base station that is suitable for sustainable internet of things and cellular networks. To the best of our knowledge, this is the first pape…

Channel Estimation Using 1-Bit Quantization and Oversampling for Large-scale Multiple-antenna Systems

Zhichao Shao, Lukas T. N. Landau, Rodrigo C. de Lamare

ICASSP 2019accepted

Large-scale multiple-antenna systems have been identified as a promising technology for the next generation of wireless systems. However, by scaling up the number of receive antennas the energy consumption will also increase. One possible solution is to use low-resolution analog-to-digital converter…
