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 ...

The upcoming Third-Generation Partnership Project—Long-Term Evolution (3GPP-LTE) cellular standard will employ spatial multiplexing to significantly increase the data rates. Detection of the spatially multiplexed signals is an essential issue in the design of an LTE receiver. In this paper, we evaluate the performance–complexity tradeoffs for a set of low-complexity multiple input multiple outp...

The development of wireless broadband access network (WBAN) leads to enhance the insufficiency of unoccupied radio resources. This is quite expected in coming times, wireless cellular technologies and wireless local area networks (WLANs) will work together in coexistence scenario within the alike unlicensed spectrums (USs). Although, two most emerging wireless networks, i.e., Long Term Evaluati...

In order to migrate toward 4G, studies on 3G LTE(Long Term Evolution) have been announced recently in the 3GPP(3rd Generation Partnership Project) and standardization is under way. Therefore, 3G LTE(Long Term Evolution) systems have been designed and developed over many countries. We also have been developing a 3G LTE testbed system at ETRI. 3G LTE system is adopting OFDM (Orthogonal Frequency ...

This paper proposes a two-dimensional spreading method in UMTS Long Term Evolution (LTE). Such method brings additional time-frequency diversity which is beneficial in terms of the ability to decode transmitted dat at the receiver side under multipath fading. Additional diversity is caused by the fact that chips of transmitted signals are spread with a Walsh-Hadamard spreading sequence over sev...
