Phase Noise Detection via Expectation Propagation and Related Algorithms
Elisa Conti, Armando Vannucci, Amina Piemontese +1
In the context of signal detection in the presence of an unknown time-varying channel parameter, receivers based on the Expectation Propagation (EP) framework appear to be very pro…
Detection for Flat-Fading Channels based on Expectation Propagation
Elisa Conti, Amina Piemontese, Giulio Colavolpe +1
This paper aims at tackling the problem of signal detection in flat-fading channels. In this context, receivers based on the expectation propagation framework appear to be very pro…
Discrete-time models and performance of phase noise channels
Amina Piemontese, Giulio Colavolpe, Thomas Eriksson
This paper deals with the phase noise affecting communication systems, where local oscillators are employed to obtain reference signals for carrier and timing synchronizations. The…
MDS-Coded Distributed Caching for Low Delay Wireless Content Delivery
Amina Piemontese, Alexandre Graell i Amat
We investigate the use of maximum distance separable (MDS) codes to cache popular content to reduce the download delay of wireless content delivery. In particular, we consider a ce…
Multiuser Detection in Multibeam Satellite Systems: Theoretical Analysis and Practical Schemes
Giulio Colavolpe, Andrea Modenini, Amina Piemontese +1
We consider the rates achievable by a user in a multibeam satellite system for unicast applications, and propose alternatives to the conventional single-user symbol-by-symbol detec…
MDS-Coded Distributed Storage for Low Delay Wireless Content Delivery
Amina Piemontese, Alexandre Graell i Amat
We address the use of maximum distance separable (MDS) codes for distributed storage (DS) to enable efficient content delivery in wireless networks. Content is stored in a number o…
Binary CPMs with Improved Spectral Efficiency
Malek Messai, Amina Piemontese, Giulio Colavolpe +2
We design new continuous phase modulation (CPM) formats which are based on the combination of a proper precoder with binary input and a ternary CPM. The proposed precoder constrain…
On the Use of Multiple Satellites to Improve the Spectral Efficiency of Broadcast Transmissions
Andrea Modenini, Alessandro Ugolini, Amina Piemontese +1
We consider the use of multiple co-located satellites to improve the spectral efficiency of broadcast transmissions. In particular, we assume that two satellites transmit on overla…
On the Application of Multiuser Detection in Multibeam Satellite Systems
Giulio Colavolpe, Andrea Modenini, Amina Piemontese +1
We study the achievable rates by a single user in multibeam satellite scenarios. We show alternatives to the conventional symbol-by-symbol detection applied at user terminals. Sing…
