Joint Power Allocation and Path Selection for Multi-Hop Noncoherent Decode and Forward UWB Communications

With the aim of extending the coverage and improving the performance of impulse radio ultra-wideband (UWB) systems, this paper focuses on developing a novel single differential encoded decode and forward (DF) non-cooperative relaying scheme (NCR). To favor ...

Successive Refinement of Gaussian Projections

Michael Christoph Gastpar, Guillaume Jean Op 't Veld

Successive refinement is a technique to encode a source iteratively, improving the distortion at each step. If the code rates of all steps combined can be as efficient as coding only for the final distortion in one go, then the source is said to be success ...

SVM Based Event Detection and Identification: Exploiting Temporal Attribute Correlations Using SensGru

Nauman Shahid

In the context of anomaly detection in cyber physical systems (CPS), spatiotemporal correlations are crucial for high detection rate. This work presents a new quarter sphere support vector machine (QS-SVM) formulation based on the novel concept of attribut ...

Analyzing and Boosting the Performance of Power-Line Communication Networks

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

Power-line communications are employed in home networking to provide easy and high-throughput connectivity. IEEE 1901, the MAC protocol for power-line networks, employs a CSMA/CA protocol similar to that of 802.11, but is substantially more complex, which ...

Control of cavity lifetime of 1.5 mu m wafer-fused VCSELs by digital mirror trimming

Elyahou Kapon, Grigore Suruceanu, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi

Digital chemical etching is used to trim the output mirror thickness of wafer-fused VCSELs emitting at a wavelength near 1.5 mu m. The fine control of the photon cavity lifetime thus achieved is employed to extract important device parameters and optimize ...

Optical sinc-shaped Nyquist pulses of exceptional quality

Luc Thévenaz, Camille Sophie Brès, Marcelo Alfonso Soto Hernandez, Mohammad Amin Shoaie, Mohammad Mehdi Alem Karladani

Sinc-shaped Nyquist pulses possess a rectangular spectrum, enabling data to be encoded in a minimum spectral bandwidth and satisfying by essence the Nyquist criterion of zero inter-symbol interference (ISI). This property makes them very attractive for com ...

Optical Nyquist-pulse generation with a power difference to the ideal sinc-shape sequence of < 1%

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Mohammad Amin Shoaie, Mohammad Mehdi Alem Karladani

Sinc-shaped Nyquist-pulses possess a rectangular spectrum. Thus, a sinc-pulse transmission minimizes the carrier spacing down to the baud rate, and therefore, substantially increases the transmissible data rates. These perspectives have led to a strong res ...
