A proximity-coupled graphene patch-based full-duplex antenna is proposed for terahertz (THz) applications. The provides a 10 dB impedance bandwidth of 6.06% (1.76 − 1.87 THz). input ports the design are isolated from each other by −25 dB. aspect ratio graphene-based radiating patch and physical parameters selected obtaining single-mode operation. dimensions (length width graphene) have been opt...

This paper presents the design and implementation of the first in-band full duplex WiFi-PHY based MIMO radios that practically achieve the theoretical doubling of throughput. Our design solves two fundamental challenges associated with MIMO full duplex: complexity and performance. Our design achieves full duplex with a cancellation design whose complexity scales almost linearly with the number ...

Full-duplex communications systems that transmit and receive simultaneously suffer self-interference due to the mixing of transmitted signal weaker received at same node. The problem becomes compounded in Multi-Input Multi-Output (MIMO) systems, where considerable overhead is dedicated training. In this article, we discuss using blind source separation techniques, namely Independent Component A...

The device in conventional half-duplex WiFi networks cannot perform carrier sensing while in data transmission; thus it suffers from long collision duration. To mitigate this problem, this chapter introduces full-duplex (FD) technology into WiFi networks. A novel CSMA/CD protocol design is first presented for singlechannel FD-WiFi, which facilitates continuous carrier sensing and transmission s...

Driven by the demand for massive and accurate sensing data to achieve wireless network intelligence under a limited available spectrum, coexistence between radar communication systems has attracted public attention. In this paper, we investigate novel dual-functional full-duplex relay aided radar-communication system where phased-array is employed at amplify-and-forward (AF) relay. A joint tran...

In this paper, we introduce an echo cancellation technique for full-duplex wireless Orthogonal Frequency Division Modulation (OFDM) communication. The novelty of the work is related to improvements in the models to compensate far-end channel and transmitter front-end, not considered before. Interference cancellation is based on Least Squares (LS) algorithm performed in two successive stages, wh...
