Spatial Modulation for Joint Radar-Communications Systems: Design, Analysis, and Hardware Prototype [PDF]
IEEE Transactions on Vehicular Technology ( Volume: 70, Issue: 3,
March 2021), 2020 Dual-function radar-communications (DFRC) systems implement radar and communication functionalities on a single platform. Jointly designing these subsystems can lead to substantial gains in performance as well as size, cost, and power consumption. In this paper, we propose a DFRC system, which utilizes generalized spatial modulation (GSM) to realize ...

Gamow Shell Model description of ${ { }^{ 40 } }$Ca(d,p) transfer reaction [PDF]
Phys. Rev. C 107, L011603 (2023), 2023 Transfer reactions are essential to determine spectroscopic factors and astrophysical reaction rates. However, their theoretical evaluation is typically effected using standard reaction theory, from which structure degrees of freedom are absent. While reaction cross sections have been implemented in the frame of the no-core shell model with continuum ...

Differential Transmission Schemes for Generalized Spatial Modulation [PDF]
, 2021 Differential modulation schemes are very relevant in receivers having power and processing limitations, as these schemes dispense with the need for knowledge of channel coefficients for symbol detection. Spatial modulation (SM) is a scheme used in multi-antenna transmission scenarios where the data is transmitted in the amplitude, phase and spatial ...

Challenges in Constraining Gravity with Cosmic Voids [PDF]
, 2022 We compare void size and clustering statistics for nDGP and $f(R)$ gravity models and GR using N-body simulations. We show how it is critical to consider the statistics derived from mock galaxy catalogs rather than the dark matter halos alone. Marked differences between the void size functions for GR and $f(R)$ models which present when voids are ...

Securing Speech in GSM Networks using DES with Random Permutation and Inversion Algorithm [PDF]
International Journal of Distributed and Parallel Systems (IJDPS)
Vol.3, No.4, July 2012, 157-164, 2012 Global System for Mobile Communications (GSM) is one of the most commonly used cellular technologies in the world. One of the objectives in mobile communication systems is the security of the exchanged data. GSM employs many cryptographic algorithms for security like A5/1, A5/2 and A5/3.

Generalized Spatial Modulation in Large-Scale Multiuser MIMO Systems [PDF]
, 2015 Generalized spatial modulation (GSM) uses $n_t$ transmit antenna elements but fewer transmit radio frequency (RF) chains, $n_{rf}$. Spatial modulation (SM) and spatial multiplexing are special cases of GSM with $n_{rf}=1$ and $n_{rf}=n_t$, respectively.

Microscopic calculations of the characteristics of radiative nuclear reactions for double-magic nuclei [PDF]
, 2015 The neutron capture cross sections and average radiative widths of neutron resonances for two double-magic nuclei 132Sn and 208Pb have been calculated using the microscopic photon strength functions, which were obtained within the microscopic self-consistent version of the extended theory of finite Fermi systems in the time blocking approximation.
