Full-Duplex Infrastructure Nodes: Achieving Long Range with Half-duplex Mobiles
… in today's wireless networks is the half-duplex constraint - the assumption that nodes cannot transmit and receive simultaneously in the same band. The reason for this constraint and the hurdle to full-duplex operation is self-interference: a node's transmit signal appears at its own …

Wireless Full-Duplex: From Practice to Theory
Full-duplex is the ability of a node to transmit and receive simultaneously in the same band. Ideal wireless full-duplex communication can double the spectral efficiency compared to the traditional half-duplex communication. In this dissertation, we study the challenges in realizing full-duplex …

Interference channels with half-duplex source cooperation
The performance gain of allowing half-duplex source cooperation is studied for Gaussian interference channels. The source cooperation is in-band, meaning that each source can listen to the other source's transmission, but there is no independent channel between the sources; half-duplex assumes …

Analogue self-interference cancellation in full-duplex radios
… the saturation of the receiver chain in full-duplex (FD) radios. This is done by cancelling the self-interference (SI) signal before it enters the receiver chain. AASIC techniques are usually implemented together with passive and active digital self-interference cancellation (SIC) techniques. …

Structural characterization of G-Quadruplexes within duplex DNA
… for characterizing these GQ structures within a duplex DNA context (i.e. a GQ structure with its complementary sequence embedded within a dsDNA context). The biological importance of these structures can be traced to GQ involvement in regulation of replication and transcription, genome …

Weldability and hydrogen relationships in super duplex stainless steel.
As the microstructure of commercial duplex stainless steels consists of approximately 50% austenite and 50% ferrite, the response of these two phases to hydrogen is of interest to the users of these materials. A study has been made of the hydrogen cracking behaviour in welded super duplex stainless …
