We propose channel estimation and direct equalization techniques for transmission over doubly selective channels. The doubly selective channel is approximated using the basis expansion model (BEM). Linear and decision feedback equalizers implemented by time-varying finite impulse response (FIR) filtersmay then be used to equalize the doubly selective channel, where the time-varying FIR filters ...

In this paper, we propose a time-varying (TV) finite impulse response (FIR) equalizer for doubly-selective (timeand frequencyselective) channels. We use the basis expansion model (BEM) to approximate the doubly-selective channel and to design the TV FIR equalizer. This structure allows us to turn a large design problem into an equivalent small design problem, containing only the BEM coefficient...

Many Standard Model extensions predict doubly-charged scalars; in particular, all models with resonances in charged lepton-pair channels with non-vanishing lepton number; if these are pair produced at the LHC, the observation of their decay into l±l±W∓W∓ will be necessary in order to establish their lepton-number violating character, which is generally not straightforward. Nonetheless, the anal...

We develop a fast method for computing the electrostatic energy and forces collection of charges in doubly-periodic slabs with jumps dielectric permittivity at slab boundaries. Our achieves spectral accuracy by using Ewald splitting to replace original Poisson equation nearly-singular sources smooth far-field equation, combined localized near-field correction. Unlike existing methods, which mak...

The dispersive optical model approach to nucleon scattering is extended from spherical nuclei to permanently deformed nuclei for the rst time. Here, a dispersive coupled channels analysis of proton and neutron scattering and reaction cross sections is presented for Ta and W for incident energies up to 200 MeV. A very good overall agreement between experimental data and predictions is achieved u...

The LHCb Collaboration announced the observation of doubly charmed baryon through $$\Xi _{c c}^{++} \rightarrow \Lambda _{c}^{+} K^{-} \pi ^{+} ^{+}$$ in 2017. Since then, a series studies heavy baryons have been presented. _{cc}^{++}$$ was discovered nonleptonic four-body decay mode, and experimental data indicated that modes c}^{++}$$ are not saturated by two- three-body intermediate states. ...
