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 ...

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.

Virtual Full-Duplex Relaying With Half-Duplex Relays
IEEE Transactions on Information Theory, 2015We 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), 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.

X-Duplex Radios: Flexible Switching Between Full-Duplex and Half-Duplex
IEEE Wireless Communications Letters, 2018Full duplex (FD) has the potential to achieve full sum rate, but in practice, may be affected by the self interference, i.e., a loop-back interference from the transmit module to its receive module, while half duplex (HD) can avoid the self interference at the expense of lower resource efficiency.

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

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.

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
