Resource and Performance Comparisons for Different Acquisition Methods that can be Applied to a VHDL-based GPS Receiver in Standalone and Assisted Cases

Pierre-André Farine, Cyril Botteron, Jérôme Leclère

There are mainly three well-known techniques to acquire a GNSS signal. The first, called Serial Search Acquisition, consist in correlating the Pseudo-Random Noise (PRN) codes for all the codes phases and all the frequency bins. The two others make use of t ...

Combinatorial algorithms for wireless information flow

Christina Fragouli, Aurore Amaudruz

A long-standing open question in information theory is to characterize the unicast capacity of a wireless relay network. The difficulty arises due to the complex signal interactions induced in the network, since the wireless channel inherently broadcasts t ...

Cryptanalysis of the ISDB Scrambling Algorithm (MULTI2)

Pouyan Sepehrdad, Jorge Nakahara, Jean-Philippe Aumasson

MULTI2 is the block cipher used in the ISDB standard for scrambling digital multimedia content. MULTI2 is used in Japan to se- cure multimedia broadcasting, including recent applications like HDTV and mobile TV. It is the only cipher speciﬁed in the 2007 J ...

Analysis of lightweight stream ciphers

Simon Fischer

Stream ciphers are fast cryptographic primitives to provide confidentiality of electronically transmitted data. They can be very suitable in environments with restricted resources, such as mobile devices or embedded systems. Practical examples are cell pho ...

A Power-Efficient Clock and Data Recovery Circuit in 0.18-um CMOS Technology for Multi-Channel Short-Haul Optical Data Communication

Seyed Armin Tajalli, Yusuf Leblebici, Paul Victor Georges Muller

This paper studies the specifications of gated-oscillator-based clock and data recovery circuits (GO CDRs) designed for short haul optical data communication systems. Jitter tolerance (JTOL) and frequency tolerance (FTOL) are analyzed and modeled as two ma ...

Fading observation alignment via feedback

Michael Christoph Gastpar

In some remote sensing applications, the functional relationship between the source being observed and the sensor readings may not be known. Because of communication constraints, this uncertainty may result in poor end-to-end distortion. If the sensors hav ...

Correlation properties of binary sequences generated by the logistic map-application to DS-CDMA

In this paper, we will show that a simple one dimension non-linear map allows generating symbolic sequences that have better statistical properties then classical pseudo random ones. Using performance criterion that is suitable for CDMA application, the pe ...

Approaching the AWGN Channel Capacity without Active Shaping

Rüdiger Urbanke, Bixio Rimoldi

It is shown that the capacity of the AWGN channel can be approached via a multilevel coding scheme with the output of each encoder mapped into an independent signal constellation. No active shaping is required in this scheme, regardless of the signal-to-no ...

Decision aid function for restoration of transmission power systems after a blackout

Tatjana Kostic

This thesis, based on a project realised in cooperation with Électricité de France (EDF), proposes a new concept for a Decision Aid Function FOr Restoration (DAFFOR) of transmission power systems after a blackout. DAFFOR is an interactive computer tool whi ...

Robustness of Gauss—Newton recursive methods: A deterministic feedback analysis

Ali H. Sayed

This paper provides a time-domain feedback analysis of the robustness performance of Gauss-Newton recursive methods that are often used in identification and control. These are recursive estimators that also involve updates of sample covariance matrices. S ...
