Published in 2024 at "IEEE Wireless Communications Letters"

DOI: 10.1109/lwc.2024.3478778

Abstract: Regularized zero-forcing (RZF) has been a cornerstone in wireless communications due to its near-optimal performance and low-complexity design. Despite extensive research on RZF, its capacity with one-bit analog-to-digital converters (ADCs) remains unexplored. This letter addresses… read more here.
