In-Band Full-Duplex Wireless Systems Overview
ICC 2021 - IEEE International Conference on Communications, 2021Detailed systems engineering is required to integrate multiple self-interference cancellation (SIC) techniques for inband full-duplex (IBFD) wireless designs enabling novel applications. These SIC methods span the propagation, analog and digital domains of a typical transceiver, and must be individually analyzed before combining them to create an IBFD ...

Full Duplex DD for In-Band D2D Communication
Wireless Personal Communications, 2020Device to device (D2D) communication is a candidate technology to ascertain the 5G wireless system. To implement the D2D communication in an in-band cellular network, device discovery (DD) is a primary and critical task. A positioning reference signal has been incorporated to discover the device in the 4G-LTE system, but the DD is still a challenge due

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.
