High Symbol Rate Coherent Optical Transmission Systems: 80 and 107 Gbaud

Rüdiger Urbanke, Luis Salamanca Miño

We demonstrate high speed optical transmission systems using digital coherent detection at all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we demonstrate a single-carrier polarization division multiplexed quadrature phase shi ...

Method for estimating and correcting a drift between clocks of receiving transceiver and a corresponding emitting transceiver, and receive for implementing said method

Jean-Yves Le Boudec, Ruben Merz

Method for estimating and correcting a frequency offset between a local clock of a receiving transceiver and a remote clock of an emitting transceiver comprises receiving by said receiving transceiver, a signal emitted by the emitting transceiver, said sig ...

Wireless Voltage Regulation for Passive Transponders Using an IF to Communicate

Catherine Dehollain, Michel Declercq

This paper presents a novel architecture for wireless communication systems made up of a base station and a remotely powered transponder. The architecture enables the base station to perform wireless voltage regulation (WVR) of the rectifier's output volta ...

Cryptography in radio frequency identification and fair exchange protocols

Gildas Avoine

This PhD thesis focuses on fair exchange protocols and radio frequency identification protocols. Fair exchange stems from a daily life problem: how can two people exchange objects (material or immaterial) fairly, that is, without anyone being hurt in the e ...
