Antenna for In-Band Full-Duplex Wireless Communications
2018 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2018In-Band Full-Duplex (IBFD) operation allows simultaneous transmission of data over the same frequency band. However, IBFD operation experiences a strong Self-Interference (SI) due to its TX-signal leaking to the receiver. This paper presents a compact dual port antenna (footprint about 0.33λ × 0.33λ) with high isolation between TX/RX ports designed ...

In-band full-duplex wireless powered communication networks
2015 17th International Conference on Advanced Communication Technology (ICACT), 2015In this paper, we consider wireless powered communication network (WPCN) in which a hybrid access point (H-AP) and user equipments (UEs) all operate in in-band full-duplex (IFD) mode. FD ability of UE allows it to harvest energy from the received energy while it transmits information in uplink (UL) at the same time, as well as that of the H-AP allows ...

Filtering Antenna Approach for In-Band Full-Duplexing Systems
2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC), 2021Self-interference cancellation (SIC) is critical for In-Band Full-Duplexing (IBFD) systems, which facilitate doubling of the spectrum efficiency [1] . Propagation-level SIC methods are especially attractive as they ease the required dynamic range of the receiver (Rx) hardware.

In-band full duplex broadband power line communications
IEEE Transactions on Communications, 2016In this paper, we introduce in-band full duplexing (IBFD) for broadband power line communication (BB-PLC) systems. Inspired by the use of IBFD in digital subscriber lines, Ethernet, cable communication, and recently in wireless communication, we investigate the constraints and requirements for a successful IBFD implementation in BB-PLC.

In-band full duplex: How it can work
2015 Asia-Pacific Microwave Conference (APMC), 2015Exploring simultaneous transmission and reception at the same carrier frequency, in-band full duplex (IBFD) has great potential to double the spectral efficiency of wireless communications. However, IBFD also creates a major problem, that is, strong self-interference, which must be suppressed to the receiver noise floor to make it work.

SIW Antenna for 5G In-Band Full Duplex Applications
2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020Ahstract-This paper presents a microstrip fed, double differential antenna based on substrate integrated waveguide (SIW) technology for In-Band Full Duplex communication at 28 GHz. Using higher order TE201 mode of the SIW cavity and differential port excitations, the proposed antenna achieves a self-interference cancellation of better than -77 dB over ...

In-band Full-Duplex communication for cognitive radio
2017 23rd Asia-Pacific Conference on Communications (APCC), 2017In this paper, we present a new Cognitive Radio (CR) paradigm based on the Full-Duplex mechanism. In the classical Full-Duplex CR (FD-CR) system, the Secondary User (SU) can examine the availability of a channel while transmitting. This fact leads to enhance the SU transmission rate.

Single antenna in-band full-duplex isolation-improvement techniques
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016Many in-band full-duplex wireless systems transmit and receive on a single antenna to minimize redundancy and maintain compact form factors. For effective operation, all of these systems need to maximize transmit-to-receive isolation, which is limited by non-ideal antenna matching and non-zero circulator leakage.

In-Band Full-Duplex Communications for Underwater Acoustic Networks
IEEE Network, 2017Driven by the increasing demand on marine exploration, UWANs are confronted with the rigorous challenge of improving network throughput. To deal with this challenge, this article proposes to apply the IBFD technique to UWANs. The IBFD technique can potentially double link capacity by simultaneously transmitting and receiving on the same frequency band,

Mixed Nash Equilibria for In-Band Full-Duplex Networks
IEEE Wireless Communications Letters, 2018This letter offers the first characterization of mixed Nash equilibria (MNE) for a wireless system with full-duplex (FD) capable terminals and slotted Aloha channel access. Focusing on a simple topology, we prove that MNE exist only if proportionality, driven by the accuracy of self-interference cancellation, is granted between the cost undergone for ...
