BER analysis of FFH/FSK system with self-normalzing receiver over intentional and unintentional interference channels by Toh, Yew Ber.

“…In this dissertation, the closed-form bit-error rate (BER) expressions for a uncoded fast frequency-hopped binary frequency-shift keying (FFH/BFSK) system using a non-linear diversity-combining receiver in the presence of multi-tone jamming (MTJ) and additive white Gaussian noise (AWGN) conditions over a non-fading channel are obtained. …”

Geometric tuning of charge and spin correlations in manganite superlattices by Rogdakis, K., Viskadourakis, Z., Petrović, A. P., Choi, E., Lee, J., Panagopoulos, C.

“…Charge transport in these heterostructures is confined to the interfaces and occurs via variable range hopping. Upon increasing n, the interfacial separation rises, leading to a suppression of the electrostatic screening between carriers of neighboring interfaces and the opening of a Coulomb gap at the Fermi level (EF ). …”

OAM-based reconfigurable doppler shifts enable PAPR reduction for multi-carrier doppler diversity by Zhao, Yufei, Ge, Yao, Yang, Zhaojie, Ju, Gaohua, Ma, Lu, Lu, Yilong, Guan, Yong Liang

“…The artificial Doppler signals can be widely used in various wireless transmission scenarios, such as Doppler spoofing stealth, Doppler index modulation, and frequency-hopping channels. As a specific example, this paper demonstrates that in the discontinuous Orthogonal Frequency Division Multiplexing (OFDM) systems, the Peak to Average Power Ratio (PAPR) degradation caused by superposition of multi-carrier signal for additional Doppler diversity can be greatly alleviated by means of the OAM-based reconfigurable Doppler shifts.…”

Bond and electronic relaxation dynamics of graphene, gold clusters, and water ice by Zhang, Xi

“…Consistency between the BOLS-TB calculation and density functional theory (DFT) calculation on graphene nanoribbons (GNRs) verified that i) the physical origin of the band gap expansion lays in the enhancement of edge potentials and hopping integrals due to the shorter and stronger bonds between undercoordinated atoms; and ii) nonbond electrons at the edge of zigzag-edged GNRs and atomic vacancies accompanied with the broken bond contribute to the Dirac-Fermi polaron (DFP) with a local magnetic momentum; iii) the formation of triple bond at the edge of armchair-edged and reconstruct-edged GNRs annihilates the nonbond electron and prevent formation of DFPs. …”
