Enabling Wireless In-band Full-duplex [PDF]

International Journal of Electronics and Telecommunications, 2019
This paper presents a baseband model and an enhanced implementation of the wireless full duplex analog method introduced by [1].Unlike usual methods based on hardware and software self- interference cancelation, the proposed design relies on FSK ...

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration

Advanced Healthcare Materials, EarlyView.
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic

Distributed Full-duplex via Wireless Side Channels: Bounds and Protocols [PDF]

, 2014
In this paper, we study a three-node full-duplex network, where a base station is engaged in simultaneous up- and downlink communication in the same frequency band with two half-duplex mobile nodes.

Semantics-Division Duplexing: A Novel Full-Duplex Paradigm

IEEE Wireless Communications
In-band full-duplex (IBFD) is a theoretically effective solution to increase the overall throughput for the future wireless communications system by enabling transmission and reception over the same time-frequency resources. However, reliable source reconstruction remains a great challenge in the practical IBFD systems due to the non-ideal elimination ...

Dynamic Full-Duplex Cellular System for Wide Area IoT Network Backbone

IEEE Open Journal of Vehicular Technology
This study proposes a dynamic full-duplex cellular (DDC) system by introducing an in-band full-duplex in a phased manner into a conventional time-division duplex (TDD)-based cellular system. Further, we propose and evaluate appropriate user equipment (UE)

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

Advanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Full-Duplex Millimeter Wave MIMO Channel Estimation: A Neural Network Approach

IEEE Transactions on Machine Learning in Communications and Networking
Millimeter wave (mmWave) multiple-input-multi-output (MIMO) is now a reality with great potential for further improvement. We study full-duplex transmissions as an effective way to improve mmWave MIMO systems. Compared to half-duplex systems, full-duplex
