Mobile traffic is projected to increase 1000 times from 2010 to 2020. This poses significant challenges on the 5th generation (5G) wireless communication system design, including network structure, air interface, key transmission schemes, multiple access, and duplexing schemes. In this paper, full duplex networking issues are discussed, aiming to provide some insights on the design and possible...

Virtual Full Duplex Wireless Networks

In this paper, full-duplex radios are used to continuously update the channel state information at the transmitter, which is required to compute the downlink precoding matrix in MIMO broadcast channels. The full-duplex operation allows leveraging channel reciprocity for open-loop uplink training to estimate the downlink channels. However, the uplink transmission of training creates interference...

Relaying is one of the useful techniques to enhance wireless physical-layer security. Existing literature shows that employing full-duplex relay instead of conventional half-duplex relay improves secrecy capacity and secrecy outage probability, but this is at the price of sophisticated implementation. As an alternative, two-path successive relaying has been proposed to emulate operation of full...

Full-Duplex Massive MIMO Multi-Pair Two-Way AF Relaying: Energy Efficiency Optimization Ekant Sharma, Rohit Budhiraja, K Vasudevan and Lajos Hanzo, Fellow IEEE Abstract We consider two-way amplify and forward relaying, where multiple full-duplex user pairs exchange information via a shared full-duplex massive multiple-input multiple-output (MIMO) relay. Most of the previous massive MIMO relayin...

Reconfigurable intelligent surfaces (RISs) have recently been presented as a revolutionary technique and recognized one of the candidates for beyond fifth-generation wireless networks. The RIS technology becomes especially attractive due to its capability operate in full-duplex (FD) mode, which is able ideally double half-duplex radio spectrum efficiency. This article analyzes performance an RI...

materials and methods in silico analysis of the cadf gene was carried out by several software and available online tools. a duplex pcr optimized with specific primers was used for detection and differentiation of both species. to evaluate specificity and sensitivity of the test, a panel of different campylobacter spp. together with several intestinal bacterial pathogens was tested. the limit of...
