Genetic-Optimized Pulse Coding Technique for Brillouin Distributed Optical Fiber Sensing

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Simon Adrien Zaslawski, Sheng Wang, Jian Wu

A single code sequence designed by a genetic searching algorithm is proposed to enhance the signal-to-noise ratio of Brillouin distributed sensors without hardware modification, enabling high-performance and cost-effective sensing over a 200-km-loop setup. ...

Secure Communication in Erasure Networks with State-feedback

László Czap

The security and efficiency of communication are two of the main concerns for networks of today and the future. Our understanding of how to efficiently send information over various channels and networks has significantly increased in the past decade (see ...

Modified parallel code-phase search for acquisition in presence of sign transition

Pierre-André Farine, Cyril Botteron, Jérôme Leclère

One of the method to have a fast acquisition of GNSS signals is the parallel code-phase search, which uses the fast Fourier transform (FFT) to perform the correlation. A problem with this method is the potential sign transition that can happen between two ...

Strategies for Delay-Limited Source-Channel Coding

Marius Kleiner

In point-to-point source-channel communication with a fidelity criterion and a transmission cost constraint, the region of achievable cost and fidelity pairs is completely characterized by Shannon's separation theorem. However, this is in general only true ...

A Robust Signal Detection Method for Ultra Wide Band (UWB) Networks with Uncontrolled Interference

Jean-Yves Le Boudec, Alaeddine El Fawal

We propose a novel detection method for non-coherent synchronization (signal acquisition) in multi-user UWB impulse radio (IR) networks. It is designed to solve the IUI (Inter-User Interference) that occurs in some ad-hoc networks where concurrent transmis ...

Cross Layer Utility of Diversity Embedded Codes

Suhas Diggavi, Sanket Dusad

Diversity embedded codes are opportunistic codes designed for the wireless fading channel. They are high-rate space-time codes which have embedded within them a high-diversity (low rate) code. In this paper, we focus on the application of diversity embedde ...

Effect of Spatio-Temporal Channel Correlation on the Performance of Space-Time Codes

Christina Fragouli

The determinant and rank criteria used for space-time code design apply at high SNR. Code design metrics developed for low SNR assume a channel autocorrelation matrix with equal eigenvalues, which does not hold in many practical scenarios. This paper shows ...

Prefiltered M-BCJR Equalizer for MIMO Frequency-Selective Channels

Christina Fragouli, Suhas Diggavi

This paper addresses the problem of soft equalization for space-time-coded transmissions over frequency-selective fading channels. The structure of the space-time code is embedded in the channel impulse response for efficient joint equalization and decodin ...

On optimal low-complexity source/channel coding

Martin Vetterli, Michael Christoph Gastpar, Bixio Rimoldi

Shannon's separation theorem gives a conceptually and practically appealing way to construct an optimal communication system in two independent steps, namely source compression and channel coding. However, sometimes it is worth considering {\em joint} sour ...
