Blind Source Separation For Full-Duplex Systems: Potential and Challenges

IEEE Open Journal of the Communications Society, 2021
Full-duplex communications systems that transmit and receive simultaneously suffer self-interference due to the mixing of the transmitted signal and the weaker received signal at the same node.

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.

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)

Inter-User Interference Cancellation Scheme for 5G-Based Dynamic Full-Duplex Cellular System

IEEE Open Journal of Vehicular Technology
Improving 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 ...

In-band full-duplex transceiver technology for 5G mobile networks [PDF]

ESSCIRC Conference 2015 - 41st European Solid-State Circuits Conference (ESSCIRC), 2015
In-band full-duplex is a promising air interface technique to tackle several of the key challenges of next generation (5G)mobile networks. Simultaneous transmission and reception in the same frequency band increases the throughput and spectral efficiency, and reduces the air interface delay. Its implementation in 5G systems, however, restrains the full-

Three-Mode Opportunistic Full-Duplex Switching

IEEE Access
This 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.

Enabling Wireless In-band Full-duplex

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 modulation.

Developing In-Band Full-Duplex Radio in FRS Band

The Journal of Korean Institute of Electromagnetic Engineering and Science, 2017
In this paper, a self-interference signal cancellation(SIC) circult for In-band Full-Duplex has been developed and tested in RF/analog region. By use of this SIC circuit, a FM two-way radio has been developed working at FRS(Family Radio Service) band.

In-Band Full-Duplex Relay-Assisted Millimeter-Wave System Design

IEEE Access, 2019
Millimeter-wave (mmWave) communication is a promising technology for future wireless systems due to the availability of huge unlicensed bandwidth. However, the need for large number of radio frequency (RF) chains associated with the antenna array and the

Vector bin-and-cancel for MIMO distributed full-duplex

EURASIP Journal on Wireless Communications and Networking, 2017
In a multi-input multi-output (MIMO) full-duplex network, where an in-band full-duplex infrastructure node communicates with two half-duplex mobiles supporting simultaneous up- and downlink flows, the inter-mobile interference between the up- and ...
