A Lower Bound on the Capacity of MIMO Channels with One-Bit ADCs

초록

One-bit ADC has been studied as a useful solution to resolve inherent problems in massive multiple-input and multiple-output (MIMO) systems and mmWave communications in 5G and beyond 5G standards. However, the capacity of a MIMO channel using one-bit ADCs is not known in an explicit form. As an alternative, upper and lower bounds have been derived in the literature. In this study, we consider a zero-forcing-based algorithm to provide a closer lower bound for the capacity of a MIMO channel with one-bit ADCs. © 2021, Korean Institute of Communications and Information Sciences.
