This letter analyzes and compares the performance of full-duplex relaying (FDR) and half-duplex relaying (HDR) for ultra-reliable short-packet communications. Specifically, we derive both approximate and asymptotic closed-form expressions of the block error rate (BLER) for FDR and HDR using short packets with finite blocklength codes. We define and attain a closed-form expression of a critical ...

Joint communication and sensing (JCAS) is a very promising 6G technology, which attracts more research attention. Compared with communication, radar has many unique features in terms of waveform design criteria, selfinterference cancellation (SIC), aperture-dependent resolution, virtual aperture. This paper proposes novel named max-aperture slicing (MaRS) to gain large time-frequency aperture, ...

In this paper, we study a communication system consisting of three end-nodes, e.g. a single transceiver base station (BS), one transmitting and one receiving user equipments (UEs), and a common two-way relay node (RN) wherein the full-duplex BS transmits to the receiving UE in downlink direction and receives from the transmitting UE in uplink direction with the help of the intermediate full-dup...

We study a multi-cell multi-user MIMO full-duplex network, where each base station (BS) has multiple antennas with full-duplex capability supporting single-antenna users with either full-duplex or half-duplex radios. We characterize the upand downlink ergodic achievable rates for the case of linear precoders and receivers. The rate analysis includes practical constraints such as imperfect selfi...

Full-duplex unmanned aerial vehicle (UAV) communication systems are characterized by mobility, so the self-interference (SI) channel characteristics change over time constantly. In full-duplex UAV systems, difficulty is to eliminate SI in time-varying channels. this paper, we propose a pilot-aid digital cancellation (SIC) method. First, pilot inserted into data sequence uniformly, and modeled a...

Covert communication can hide the information transmission process from warden to prevent adversarial eavesdropping. However, it becomes challenging when location of is uncertain. In this paper, we propose a covert scheme against with uncertain locations, which maximizes connectivity throughput between multi-antenna transmitter and full-duplex jamming receiver limit outage probability (the foun...

Ultra-reliable low-latency communication (URLLC) is one of the most important components in fifth generation (5G) cellular networks for realizing mission-critical applications. In this paper, we jointly optimize transceiver design and decoding error probability (DEP) a full-duplex (FD) URLLC system, where base station (BS) operates FD mode, while uplink (UL) downlink (DL) users work half-duplex...

Abstract A new cost-effective mobile fronthaul architecture has been proposed by designing promising analog radio over fiber (ARoF) transmission system compliant with the next generation ultra-dense wavelength division multiplexing passive optical network (UDWDM-PON). It is conceived for standalone 5G/5G+ communication systems driven broadband multi-input multi-output (MIMO) millimeter wave dat...
