Multicarrier Division Duplex Aided Millimeter Wave Communications
IEEE Access, 2019 The existing time-division duplex (TDD) and frequency-division duplex (FDD) techniques rely on a guard time and/or a guard band to avoid self-interference (SI) between the uplink and downlink channels, which results in the wastage of precious spectral ...

Beamforming Design for In-Band Full-Duplex Multi-Cell Multi-User MIMO LSA Cellular Networks
IEEE Access, 2020 The in-band full-duplex (IBFD) mechanism offers many advantages over standard half duplex (HD) systems: it can potentially double the capacity and increase spectrum utilization efficiency. While IBFD renders many conventional research problems irrelevant,

IEEE Journal on Selected Areas in Communications, 2017 In this paper, the problem of uplink (UL) and downlink (DL) resource optimization, mode selection and power allocation is studied for wireless cellular networks under the assumption of in-band full duplex (IBFD) base stations, non-orthogonal multiple access (NOMA) operation, and queue stability constraints.

Throughput of distributed queueing-based LoRa for long-distance communication
EURASIP Journal on Advances in Signal Processing, 2021 LoRa, due to its advantage of long-range communication capability, is promising for Internet of Things (IoT) and space-air-ground communications. However, the conventional MAC protocol used with LoRa is classified as an Aloha-based algorithm, which leads

Wireless Communications and Mobile Computing, Volume 2019, Issue 1, 2019., 2019 In this paper, we analyze the performance of a full‐duplex (FD) amplify‐and‐forward (AF) relay system with imperfect hardware. Besides the aggregate hardware impairments of the imperfect transceiver, we also consider the impact of residual self‐interference (RSI) due to imperfect cancellation at the FD relay node.
