Full-duplex relaying communication

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
In this work, data signaling rates and error performances of half-duplex and full-duplex relaying/cooperative systems in flat fading channels are investigated in ideal and non-ideal self interference cancellation cases. A hybrid relaying system that is able to choose between full-duplex or half-duplex transmission according to the value of self ...

Integrated full duplex radios

IEEE Communications Magazine, 2017
Full duplex wireless has drawn significant interest in the recent past due to the potential for doubling network capacity in the physical layer and offering numerous other benefits at higher layers. However, the implementation of integrated full duplex radios is fraught with several fundamental challenges.

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.

Spatial Modulated Full Duplex

IEEE Wireless Communications Letters, 2014
This letter proposes spatial modulated full duplex (SMFD), which applies spatial modulation to a point-to-point full-duplex communication system. The spatial modulation transmits its information bits by transmit antenna selection in addition to symbol modulation, whereas the full-duplex (FD) technique suppresses self-interference leaking from the ...

Full-duplex without strings

Proceedings of the 20th annual international conference on Mobile computing and networking, 2014
Enabling wireless full-duplex (from an AP) with multiple half-duplex (HD) clients is key to widespread adoption of full-duplex (FD) in commercial networks. However, enabling FD in such networks is fundamentally challenged by a new form of uplink-downlink interference (UDI), arising between HD clients operating simultaneously in the uplink and downlink ...

Asynchronous full-duplex wireless

2012 Fourth International Conference on Communication Systems and Networks (COMSNETS 2012), 2012
The feasibility of a full-duplex physical layer, where a node can transmit and receive at the same time in the same frequency, has been established in recent work. Implicitly, most schemes to-date have assumed synchronous operation which allows clean training of all relevant channels.

In-Band Full-Duplex Technology: Techniques and Systems Survey

IEEE transactions on microwave theory and techniques, 2019
In-band full-duplex (IBFD) technology can enable unique system capabilities and network architectures by allowing devices to transmit and receive on the same frequency at the same time. While previously considered impossible, this ability can now be used

Full-Duplex Communication Systems

2019
In contrast to conventional half-duplex (HD) transceivers, a full-duplex (FD) transceiver is able to transmit and receive simultaneously in the same frequency band. The main impediment for FD implementation is the self-interference (SI) caused by the strong coupling of the transmitted signal to the receiver chain. Self-interference is usually mitigated

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.

A cooperative jamming protocol for full-duplex relaying with full-duplex receiver

2016 8th International Conference on Wireless Communications & Signal Processing (WCSP), 2016
This paper investigates the secrecy performance of a full-duplex relaying (FDR) system with a full-duplex (FD) receiver. A novel cooperative jamming protocol is proposed to improve physical layer security, where the FD receiver sends interference to the eavesdropper to degrade its received signal-to-noise ratio when receiving signals from the relay and
