ملخص الدراسة: Quadrature spatial modulation (QSM) has been recently proposed for MIMO communication systems. It comes to enhance the overall throughput over conventional spatial modulation (SM) techniques. This article investigates the using of this new SM technique in Multi-user MIMO networks, denoted here as MU-QSM. Unlike existing SM techniques, the QSM creates additional spatial constellation […]

ملخص الدراسة: In a time of catastrophes like war or earthquake,_x000D__x000D_ people forced to leave their houses and live in tents or remote_x000D__x000D_ areas. In both cases, utilities such as electricity, hot water, and_x000D__x000D_ probably toilet need to be provided urgently. Maker movement_x000D__x000D_ creates a creativity on the mind of engineers. Engineers use_x000D__x000D_ knowledge, which […]

ملخص الدراسة: Conventional methods of traffic light systems are unable to deal with the ongoing issues surrounding congestion. The current traffic light models are not suited to tackle problems such as traffic jams, ease of access for emergency vehicles and prevention of accidents. In order to counteract these issues, we propose the ‘Smart traffic light […]

ملخص الدراسة: Penetration of renewable resources increases the global demand for high-efficient Energy Storage Technology (EST) that deals with reduction in the emission of green-house gases causing environmental hazards/pollutions, thereby ensures cleaner environment and more reliable energy storing systems. This article provides a mini review on various types of Electrical Energy Storage Technologies (EEST), which […]

ملخص الدراسة: Orthogonal frequency-division multiplexing (OFDM) systems suffer from significant out-of-band (OOB) radiation. All existing techniques have several drawbacks as wasting spectral or time resources. Time domain windowing is a well-known technique where an extended smoothing window is multiplied by the modulated signal. This window reduces the signal spectrum sidelobes, however, it extends the resource […]

ملخص الدراسة: In this work, dispersion characteristics and sensitivity of the propagation of TM surface plasmon through the proposed waveguide sensor. The proposed sensor containing a graphene at a finite distance filled with metamaterials (MTM) from plasmonic layer and sandwiched by dielectric layers. We numerically demonstrate the proposed waveguide structure as a novel graphene surface […]

ملخص الدراسة: The characteristics of a three-layer waveguide is studied. The waveguide structure consists of a thin layer of graphene at the interface between air and a dielectric layer at a distance d from nonlinear media. The dispersion equation of the waveguide is derived from Maxwell’s equations and numerically solved using Maple 17. The first […]

A new spatial modulation_x000D__x000D_ technique, termed signed quadrature spatial modulation (SQSM),_x000D__x000D_ is introduced in this paper. Unlike QSM, SQSM creates fourdimensional_x000D__x000D_ spatial […]

ملخص الدراسة: Double spatial modulation (DSM) is a transmission technique which has been recently proposed for multipleinput multiple-output (MIMO) communication systems. DSM has a higher spectral efficiency compared with_x000D__x000D_ classical spatial modulation (SM), as it doubles the number of active transmit antennas. In this paper, transmit_x000D__x000D_ antenna selection (TAS) is applied to DSM in order […]

ملخص الدراسة: The Gaza Strip has been suffering from extreme conditions of political conflicts, underdevelopment, poverty, shortage and salinity of water, etc. Most of these conditions resulted from extreme human behavior creating real disasters. Natural disasters had been known since long time, and recently, human disasters became more understandable after several wars had resulted in […]
