Compensation of Phase Noise in OFDM Wireless Systems

Ali H. Sayed

Phase noise causes significant degradation in the performance of orthogonal frequency division multiplexing (OFDM)-based wireless communication systems. The presence of phase noise can reduce the effective signal-to-noise ratio (SNR) at the receiver, and c ...

Performance Analysis of Multiband OFDM UWB Communications With Application to Range Improvement

Ali H. Sayed

Ultrawideband (UWB) radio is a promising solution for high-rate wireless communications over short ranges. In this paper, the performance of multiband orthogonal frequency division multiplexing (MB-OFDM) UWB systems is analyzed using the Saleh-Valenzuela c ...

Towards Reliable Broadcasting using ACKs

Patrick Thiran, Christina Fragouli, Mathilde Durvy

We propose a mechanism for reliable broadcasting in wireless networks, that consists of two components: a method for bandwidth efficient acknowledgment collection, and a coding scheme that uses acknowledgments. Our approach combines ideas from network codi ...

Secure Neighbor Discovery in Wireless Networks: Formal Investigation of Possiblity

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

Wireless communication enables a broad spectrum of applications, ranging from commodity to tactical systems. Neighbor discovery (ND), that is, determining which devices are within direct radio communication, is a building block of network protocols and app ...

Exact Capacity Scaling of Extended Wireless Networks

Olivier Lévêque, Ayfer Özgür Aydin

n source and destination pairs randomly located in an area extending linearly with n want to communicate with each other. Signals transmitted from one user to another at distance r apart are subject to a power attenuation of r^{-alpha} and random phase cha ...

Multi-hop Broadcast from Theory to Reality: Practical Design for Ad Hoc Networks

Jean-Yves Le Boudec, Alaeddine El Fawal

We propose a complete design for a scope limited, multi-hop broadcast middleware, which is adapted to the variability of the ad-hoc environment and works in unlimited ad-hoc networks such as a crowd in a city, or car passengers in a busy highway system. We ...

Vulnerabilities in Epidemic Forwarding

Jean-Yves Le Boudec, Alaeddine El Fawal

We identify vulnerabilities in epidemic forwarding. We address broadcast applications over wireless ad-hoc networks. Epidemic forwarding employs several mechanisms such as inhibition and spread control, and each of them can be implemented using alternative ...
