Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020 In this paper, we analyze the performance of in‐band full‐duplex (IBFD) relay systems that use the decode‐and‐forward (DF) protocol at the relay under the impact of imperfect self‐interference cancellation and hardware impairments. Three practical relay scenarios are considered in our analysis: (i) there is no direct link from the source to the ...

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,

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.

Design and Implementation of an End-to-End Amplify and Forward Full-Duplex Relay Network
IEEE Access, 2020 This paper presents the design and implementation of an In-Band Full-Duplex (IBFD) amplify and forward relay for wireless networks. First, we describe the system model of the full-duplex relay (FDR), where the relay extends the range of the source node ...

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
