In this brief we present a design of full-duplex (FD) underwater acoustic communication (UAC) receiver with two-sensor transducer. The transducer consists two piezo-ceramic cylinders cast together in polyurethane resin; one acts as hydrophone and the other projector. As distance between projector is extremely short, high level self-interference (SI) from received at hydrophone. This SI must be ...

In this paper, the MIMO full-duplex system is proposed to remove self-interference signal using modified DFT based channel estimation technique. In SISO full-duplex systems only single transceiver can transmit data on either side simultaneously whereas in MIMO full-duplex systems multiple transceivers can transmit data simultaneously from both sides. During MIMO full-duplex transmission self-in...

Recent work has shown the feasibility of single-channel fullduplex wireless physical layer, allowing nodes to send and receive in the same frequency band at the same time. In this report, we first design and implement a real-time 64subcarrier 10 MHz full-duplex OFDM physical layer, FDPHY. The proposed FD-PHY not only allows synchronous full-duplex transmissions but also selective asynchronous f...

The challenge to in-band full-duplex wireless communication is managing self-interference. Many designs have employed spatial isolation mechanisms, such as shielding or multi-antenna beamforming, to isolate the self-interference wave from the receiver. Such spatial isolation methods are effective, but by confining the transmit and receive signals to a subset of the available space, the full spa...

We consider a general multiple antenna network with multiple sources, multiple destinations and multiple relays in terms of the diversity-multiplexing tradeoff (DMT). We examine several subcases of this most general problem taking into account the processing capability of the relays (half-duplex or full-duplex), and the network geometry (clustered or non-clustered). We first study the multiple ...

This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...

It was recently studied how to achieve the optimal degrees of freedom (DoF) in a 1 multi-antenna full-duplex system with partial channel state information (CSI). In this paper, we revisit 2 the DoF of a multiple-antenna full-duplex system using opportunistic transmission under the partial 3 CSI, in which a full-duplex base station having M transmit antennas and M receive antennas supports 4 a s...

This letter considers secrecy simultaneous wireless information and power transfer (SWIPT) in full duplex systems. In such a system, full duplex capable base station (FD-BS) is designed to transmit data to one downlink user and concurrently receive data from one uplink user, while one idle user harvests the radio-frequency (RF) signals energy to extend its lifetime. Moreover, to prevent eavesdr...

Unmanned aerial vehicle (UAV)-aided two-way relaying networks are designed, where a UAV is deployed to assist multiple pairs of users in their information exchange. There two basic approaches for the user pairs' exchange within single time slot via relay. The first approach based on full-duplex, all participants operate full-duplex mode transmit and receive signals simultaneously. However, tran...
