Full duplex relaying for local area

2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013
We consider full-duplex multi-hop forwarding in a Beyond 4G local area network. In the network, there is a high density of self-backhauling relay nodes that simultaneously act as access points towards the users, in addition to few nodes with wired backhaul.

Full-duplex radios for vehicular communications

IEEE Communications Magazine, 2017
Recent significant advances in self-interference cancellation techniques pave the way for the deployment of full-duplex wireless transceivers capable of concurrent transmission and reception on the same channel. Despite the promise to theoretically double the spectrum efficiency, full-duplex prototyping in off-the-shelf chips of mobile devices is still

Full duplex communications

IEEE Communications Magazine, 2020
With the rapidly growing demand for mobile applications, future wireless networks are facing considerable challenges in spectral efficiency. To deal with it, many techniques have been developed recently. Among them, in-band full duplex (IBFD), which enables a device to transmit and receive simultaneously at the same frequency, has ignited great ...

Full-duplex speakerphone

The Journal of the Acoustical Society of America, 1993
Disclosed is an adaptive Finite Impulse Response ("FIR") filter speakerphone that provides improved echo cancelation by the inclusion of a tracking comb filter having nulls which change to track the voice portion of communications. The speakerphone also includes a pair of ambient noise recorders for recording both ambient background noise received from

Capacity Gain of Full Duplex Self-Backhauling and Opportunistic Full Duplex Self-Backhauling

IEEE Transactions on Vehicular Technology, 2021
This paper investigates the capacity gain of full duplex (FD) self-backhauling over the half duplex (HD) counterpart in downlink cellular systems, and then proposes an opportunistic FD scheme. The first step is to derive the capacity gain of FD self-backhauling over the HD counterpart as a function of the system parameters in a computationally ...

Friendly Full Duplex: A Multi-User Full Duplex Method for MGfast in Coexistence with G.fast

2018 IEEE Global Communications Conference (GLOBECOM), 2018
Multi-user full duplex (FDX) transmission is instrumental to provide sufficient coverage and reach for the multi-gigabit data rates targeted by MGfast. However, to seamlessly introduce such a technology into access networks, it is important to consider coexistence with legacy half duplex G.fast.

On the performance of full duplex wireless networks

2013 47th Annual Conference on Information Sciences and Systems (CISS), 2013
Half duplex radios use two separate frequency bands to enable simultaneous transmission and reception. Recently, full duplex radio that allows a wireless node to transmit and receive simultaneously in one frequency band was proposed. We propose a MAC protocol for full duplex radio networks, FDMAC, which is a simple and efficient protocol compatible ...

Full Duplex DOCSIS: Opportunities and Challenges

IEEE Communications Magazine, 2019
The recently released full duplex extensions to the DOCSIS 3.1 standard (FDX DOCSIS) promise to greatly alleviate the shortage of upstream bandwidth that has plagued HFC networks since inception. However, there are a number of technical and implementation challenges in both the MAC and PHY layers of FDX DOCSIS that must be overcome in order for the ...

Full duplex speakerphone

The Journal of the Acoustical Society of America, 1998
A full duplex speakerphone for connection to a telephone system employs adaptive FIR filters for acoustic and electrical echo cancellation in a novel combination with analog gain controls responsive to incoming signal levels and a transmit level control responsive to the receive signal power level.

Full-Duplex Media-Based Modulation

2017 IEEE Globecom Workshops (GC Wkshps), 2017
Media-based modulation (MBM) is an attractive modulation scheme that offers MIMO benefits by placing digitally controlled parasitic elements as radio frequency (RF) mirrors near the transmit antenna. Different realizations of the ON/OFF status of these mirrors result in different channel fades which constitute the channel modulation alphabet.
