Dynamic Full-Duplex Cellular System for Wide Area IoT Network Backbone
IEEE Open Journal of Vehicular TechnologyThis 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)

A Real-Time Wideband Subband LMS Algorithm for Full-Duplex Communications
IEEE Access, 2022 In-band full-duplex (IBFD) communications has the potential to nearly double the spectrum efficiency of existing 5G communications. Digital signal processing to mitigate self-interference is one way to realize this full-duplex capability.

Inter-User Interference Cancellation Scheme for 5G-Based Dynamic Full-Duplex Cellular System
IEEE Open Journal of Vehicular TechnologyImproving spectral efficiency is an important issue for the next generation of the 5th generation mobile communication (5G) systems. Full-duplex cellular (FDC) and dynamic-FDC (DDC) systems based on the 5G signal format (5G-FDC and 5G-DDC) have gained ...

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 ...

An in-band full-duplex radio receiver with a passive vector modulator downmixer for self-interference cancellation [PDF]
, 2015 In-band full-duplex (FD) wireless, i.e., simultaneous transmission and reception at the same frequency, introduces strong self-interference (SI) that masks the signal to be received.

Three-Mode Opportunistic Full-Duplex Switching
IEEE AccessThis paper proposes a novel opportunistic full-duplex (FD) scheme switching among three duplex modes (DMs) of half duplex (HD), three node FD (TNFD) and bidirectional FD (BiFD) for the cellular systems.

Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

A Signal-Space Analysis of Spatial Self-Interference Isolation for Full-Duplex Wireless
, 2014 The challenge to in-band full-duplex wireless communication is managing self-interference. Many designs have employed spatial isolation mechanisms, such as shielding or multi-antenna beamforming, to isolate the self-interference wave from the receiver ...
