Asynchronous full-duplex wireless
2012 Fourth International Conference on Communication Systems and Networks (COMSNETS 2012), 2012The 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.

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 ...

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 ...

Full Duplex-Aware Backoff for Improving Channel Utilization in Full Duplex WLANs
2018 International Conference on Information and Communication Technology Convergence (ICTC), 2018Even 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), 2013We 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, 2017Recent 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

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, 2021This 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), 2018Multi-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.
