The LTE Saha–Boltzman plasma ionization balance model and the Braginskii plasma electric resistance model are compared with the results by the suit of codes based on the average atom model, which is a quantum-mechanical version of the Temperature Dependent Thomas–Fermi Theory. The analysis is focused on low-Z Al, mid-Z Cu and higher-Z Mo plasmas in a broad ranges of electron temperature Te and ...

The role of optical Fe iii absorption lines in B-type stars as iron abundance diagnostics is considered. To date, ultraviolet Fe lines have been widely used in B-type stars, although line blending can severely hinder their diagnostic power. Using optical spectra, covering a wavelength range ∼ 3560 – 9200 Å, a sample of Galactic B-type main-sequence and supergiant stars of spectral types B0.5 to...

LTE-Advanced (LTE-A) proposed by the 3rd Generation Partnership Project (3GPP) has successfully applied to the International Telecommunication Union (ITU) in 2010 to be accepted as an IMT-Advanced (IMT-A) compliant 4G mobile radio system. As part of this application 3GPP has provided LTE-A system level simulation results for cell spectral efficiency and cell edge user spectral efficiency. The I...

Railway environments cannot be away from the current evolution of public communication systems. The Long Term Evolution (LTE) mobile communication system is considered to be the natural evolution for current Global System for Mobile Communications Railways (GSM-R). LTE all IP networking technology plays a key role for the integration and convergence of heterogeneous networks and services, both ...

Carrier Aggregation (CA) is one of the important features of Long Term EvolutionAdvanced (LTE-Advanced), which is being standardized in Third Generation Partnership Project (3GPP) as part of LTE Release 10. This study also presents throughput results based on different parameters; Beyond 20 MHz, the only reasonable way to achieve LTE-Advanced highest target peak-throughput rate is to increase t...

The 3rd Generation Partnership Project (3GPP) is ready to present a new cellular network standard; Long Term Evolution (LTE). LTE improves communication for public safety users like police, medical, and rescue workers in cellular networks. This creates a need to examine whether LTE can satisfy public safety users requirements. This thesis has a focus on group communication with a voice service....

This paper presents a compatibility study between future digital television (DTV) and Long Term Evolution (LTE) in the UHF band using Nigeria as a case study. This is done by carrying out an adjacent interference analysis to evaluate the impact of LTE base station on DVB-T2 reception using SEAMCAT software. Results obtained from simulations suggest that deploying LTE in an adjacent band would r...

Cysteinyl leukotrienes (CysLTs: leukotrienes C(4), D(4), and E(4)) have long been implicated in the pathogenesis of asthma and several allergic diseases. LTE(4) has been identified as a major metabolite of LTC(4), and urinary LTE(4) (U-LTE(4)) is considered as the most reliable analytic parameter for monitoring the endogenous synthesis of CysLTs. From recent studies on the U-LTE(4) associated w...

5G New Radio (NR) operating in the unlicensed spectrum is accelerating the Fourth Industrial Revolution by supporting Internet of Things (IoT) networks or Industrial IoT deployments. Specifically, LTE-Advanced (LTE-A) is looking to achieve spectrum integration through coexistence with multi-radio access technology (RAT) systems in the same unlicensed bands with both licensed-assisted and stand-...

Long Term Evolution (LTE) Advanced is the next generation of the LTE standard, offering peak data rates of up to 1 Gbps using up to 100 MHz of spectrum. A key mechanism in achieving this is carrier aggregation (CA) whereby multiple LTE component carriers (CCs) are combined in a contiguous or non-contiguous fashion. With the introduction of CA comes the challenge of network rendezvous. In order ...
