Long Term Evolution Advanced (LTE-Advanced) network is the continuation of 3GPP-LTE (3GPP: 3rd Generation Partnership Project) and it targets to advanced develop of the requirements of LTE in terms of throughput and coverage. Then, LTEAdvanced is not new as a radio access technology, but it’s an evolution of LTE to enhance the performance. The direct employment of the existing protocols cannot ...

The Long Term Evolution (LTE) is the latest mobile standard being implemented globally to provide connectivity and access to advanced services for personal mobile devices. Moreover, LTE networks are considered to be one of the main pillars for the deployment of Machine to Machine (M2M) communication systems and the spread of the Internet of Things (IoT). As an enabler for advanced communication...

Aims. Hydrogen and helium line spectra are crucial diagnostic features for the quantitative analysis of OB stars. We compute synthetic spectra based on a hybrid non-LTE approach in order to test the ability of these models to reproduce high-resolution and high-S/N spectra of dwarf and giant stars and also to compare them with published grids of non-LTE (OSTAR2002) and LTE (Padova) models. Metho...

The merits of 3GPP long term evolution (LTE), such as high spectral efficiency, very low latency, support of variable bandwidth, simple architecture, etc, make it the most competitive candidate for the next generation mobile communications standard. In the first release of LTE, only single transmit antenna is supported in the uplink due to its simplicity and acceptable performance. However, in ...

With the explosive growth in mobile data traffic fueled by smartphones and mobile applications, transition from the 3rd generation (3G) toward 4th generation (4G) cellular networks is progressing at an unprecedented pace. Since the first release (release 8) of the 3rd generation partnership project (3GPP) long-term evolution (LTE) standard in December 2008, LTE has become the de facto standard ...

Release 8 (hereinafter referred to as “LTE Rel. 8”) specifications [1][2] which completed standardization by the 3GPP in the spring of 2009. LTE Rel. 8 adopts various high-level radio interface technologies such as orthogonal multi-access, frequency-domain scheduling and Multiple Input Multiple Output (MIMO) *2 , and provides even higher system capacity and cell edge user throughput than High S...

This paper introduces an experimental testbed developed at the University of Malaga to analyze the behavior of mobile applications and services over LTE (Long Term Evolution) networks. The novelty of the testbed is the ability to correlate the impact of radio propagation issues on LTE configurations and applications protocols and cross tuning LTE parameters and IP protocols from the point of vi...

The industry landscape in telecommunications is changing rapidly at the moment. Services are increasingly shifting from voice to data and from circuit-switched to packet-switched ones. LTE and WiMAX are the two technologies poised to dominate next generation mobile networks. Battle between LTE & WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards thr...

This paper provides a high-level overview of some technology components currently considered for the evolution of LTE, referred to as LTE-Advanced. First, a brief overview of LTE and some of its technologies are given and then the IMT-Advanced requirements are discussed. One of the targets with the evolution of LTE is to reach or seven surpass these requirements. The technology components consi...
