DOI: 10.1109/lpt.2025.3567861
Abstract: The most sensitive photodetectors that can be used in optical wireless communication (OWC) receivers are silicon photomultipliers (SiPMs). Unfortunately, in addition to the usual finite bandwidth, these devices have a non-linear response. Evidence is presented… read more here.

DOI: 10.1109/tvt.2022.3146423
Abstract: Faster-than-Nyquist signaling (FTNS) has emerged as a promising technique to increase communication capacity in bandwidth-limited channels. However, the presence of FTN-induced inter-symbol interference (FTN-ISI) in the received observations, is detrimental to channel estimation (CE) and… read more here.

DOI: 10.1109/tvt.2025.3541278
Abstract: The spatial diversity and multiplexing advantages of massive multi-input-multi-output (mMIMO) can significantly improve the capacity of massive non-orthogonal multiple access (NOMA) in machine type communications. However, state-of-the-art grant-free massive NOMA schemes for mMIMO systems require… read more here.

DOI: 10.1364/ao.460839
Abstract: Non-orthogonal multiple access (NOMA) via power domain multiplexing is widely deployed in bandwidth-limited light-emitting-diode-based visible-light-communication (VLC) systems due to its excellent spectral efficiency. However, quadrature phase-shift keying (QPSK) or even lower-order modulation formats are dominant;… read more here.
