Massive MU-MIMO-OFDM Uplink with Direct RF-Sampling and 1-Bit ADCs
(2019)2019 IEEE Globecom Workshops (GC Wkshps)Advances in analog-to-digital converter (ADC) technology have opened up the possibility to directly digitize wideband radio frequency (RF) signals, avoiding the need for analog down-conversion. In this work, we consider an orthogonal frequency-division multiplexing (OFDM)-based massive multi-user (MU) multiple-input multiple-output (MIMO) uplink system that relies on direct RF-sampling at the base station and digitizes the received RF ...Conference Paper
