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 ...

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

Full-Duplex Cellular Networks

IEEE Communications Magazine, 2017
Full-duplex (FD) communications with simultaneous transmission and reception on the same carrier have long been deemed a promising way to boost spectrum efficiency, but hindered by the techniques for self-interference cancellation (SIC). Recent breakthroughs in analog and digital signal processing yield the feasibility of over 100 dB SIC capability ...

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 ...

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.

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 ...

Virtual Full-Duplex Relaying With Half-Duplex Relays

IEEE Transactions on Information Theory, 2015
We consider virtual full-duplex relaying by means of half-duplex relays. In this configuration, each relay stage in a multihop relaying network is formed by at least two relays, used alternatively in transmit and receive modes, such that while one relay transmits its signal to the next stage, the other relay receives a signal from the previous stage ...

Full Duplex-Aware Backoff for Improving Channel Utilization in Full Duplex WLANs

2018 International Conference on Information and Communication Technology Convergence (ICTC), 2018
Even though full duplex (FD) communication, which allows simultaneous transmission and reception on the same frequency channel, is a promising technology to improve the throughput in wireless local area networks (WLANs), it suffers from under-utilization when communication patterns are asymmetric.

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
