Looking Inside Modern Receivers

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain

The principle of wireless communications originates from the need to communicate between two points separated by a distance sufficiently large to prevent the use of wires. This article talks about modern receivers in which the basic building blocks of mode ...

Is Non-Unique Decoding Necessary?

Suhas Diggavi, Vinod Malathidevi Prabhakaran, Shirin Saeedi Bidokhti

In mutiterminal communication systems, signals carrying messages meant for different destinations are often observed together at any given destination receiver. Han and Kobayashi (1981) proposed a receiving strategy which performs a joint decoding of messa ...

This paper brings additional light on the previously proposed two-step tracking algorithm for E1 CBOC tracking. More specifically, assessment of the different DLL and PLL tracking loop architectures are analyzed, taking into consideration coherent and non- ...

Inst Navigation2011

In a previous project, a 7.2g helicopter made of carbon was designed and realized at the LAI. The goal of this project is to design and realize a tiny receiver and a remote capable of driving the helicopter from a distance of 2 to 4 meters. Challenges are ...

Interference Robustness and Security of Impulse-Radio Ultra-Wide Band Networks

Manuel Flury

In this thesis we study Impulse-Radio Ultra-Wide Band (IR-UWB), a physical layer radio technology offering many features that make it a promising choice for future short-range wireless networks. The challenges in such networks are many, ranging from the co ...

Effectiveness of Distance-Decreasing Attacks Against Impulse Radio Ranging

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski, Manuel Flury

We expose the vulnerability of an emerging wireless ranging technology, impulse radio ultra-wide band (IR-UWB), to distance-decreasing attacks on the physical communication layer (PHY). These attacks violate the security of secure ranging protocols that al ...

Characterization of the secrecy region of a single relay cooperative system

Ninoslav Marina

Security is an important aspect for the future wire- less networks. Since the number of network nodes increases con- stantly, and, in addition, the networks are decentralized and ad- hoc in nature, it becomes more challenging to apply the current cryptogra ...

Neighbor discovery is essential for the process of self-organization of a wireless network, where almost all routing and medium access protocols need knowledge of one-hop neighbors. In this paper we study the problem of neighbor discovery in a static and s ...

A Low-Power Dual-Frequency RF Front-End Architecture for GNSS Receivers

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain

With the availability in the years to come of several new Global Navigation Satellite Systems transmitting signals located in different frequency bands, the question of the feasibility of multi-frequency receivers aimed at the mass market is of major inter ...

The Cicada Attack: Degradation and Denial of Service in IR Ranging

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski, Manuel Flury

We demonstrate that an interferer with malicious intentions can significantly degrade the performance of impulse radio (IR) ranging. The cicada attack we have developed can decrease the distance (degradation of service) measured by ranging algorithms desig ...
