Multipath Mitigation Techniques for CBOC, TMBOC and AltBOC Signals using Advanced Correlators Architectures

Pierre-André Farine, Cyril Botteron, Aleksandar Jovanovic, Youssef Tawk

Multipath mitigation in urban canyons and indoor environments is an open issue for the reception of GNSS signals for high precision applications, as the presence of multipath components can lead to signal fading and ranging errors. New families of navigati ...

Concurrent Multipath Transferring in IP Networks: Two IP-level solutions for TCP and UDP

Maysam Yabandeh

Having multiple network interfaces or gateways available, the Internet users can transfer their data through multiple paths to achieve load balancing, fault-tolerance, and more aggregate bandwidth. However, transferring the packets of the same flow over mu ...

Signification of the phase function parameter gamma explored with a fractal distribution of scatterers

Christian Depeursinge, Pierre Marquet, Stéphane Chamot, Elena Migacheva

The optical properties within limited volumes of diffusive media can be probed by carrying spatially-resolved measurements of diffused light at short source-detector separation (typically one scattering mean free path). At such distance, analytical models ...

Exploiting the Path Propagation Time in Multipath Transmission with FEC

We consider a transmission of a delay-sensitive data stream from a single source to a single destination. The reliability of this transmission may suffer from bursty packet losses - the predominant type of failures in today's Internet. An effective and wel ...

A multi-band PLL based tuning circuitry for the super-regenerative IR-UWB receiver system

Catherine Dehollain, Michel Declercq

The impulse radio-ultra wide band (IR-UWB) signalling format has been an attractive mode for wireless communication in wireless sensor node system. The super-regenerative principle can be used for impulse reception for its inherent advantages. The oscillat ...

Ergodic Interference Alignment

Michael Christoph Gastpar

Consider a K-user interference channel with time-varying fading. At any particular time, each receiver will see a signal from most transmitters. The standard approach to such a scenario results in each transmitter-receiver pair achieving a rate proportiona ...
