We consider realistic satellite communications systems for broadband and broadcasting
applications, based on frequency-division-multiplexed linear modulations, where spectral …

We investigate the application of time and frequency packing techniques, an extension of the
classical faster-than-Nyquist signaling, to long-haul optical links. These techniques provide …

The 5G ecosystem is radically shifting Information and Communication Technologies (ICT)
towards a system directly tailored and optimised to support vertical markets and services. In …

We consider detection over linear channels impaired by additive white Gaussian noise. For
this general model, which describes a large variety of scenarios, novel detection algorithms …

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 detection …

We propose novel detection algorithms for linear modulations transmitted over nonlinear
satellite channels, also impaired by additive white Gaussian noise. These algorithms are …

In this paper, we consider the design of spiral constellations for channels affected by phase
noise. The strength of the proposed constellations resides both on the performance and on …

Non-terrestrial networks will play a crucial role in future wireless 6G systems to ensure ubiquitous
connectivity and to complement terrestrial networks. With reference to a low Earth orbit …

We consider a terrestrial wireless channel, whose statistical model under flat-fading
conditions is due to Clarke. A lot of papers in the literature deal with receivers for this scenario, …

This letter addresses the problem of signal detection in flat-fading channels. In this context,
receivers based on the expectation propagation framework appear to be very promising …
