The radio signals possessing both good correlation properties and high structural complexity provide steady operation of wireless communication systems in hostile radio - electronic environment. With regard to this fact, in the paper we propose a new ...

Transmission lines are basically described by their per-unit-length parameters. The computation of these parameters is a critical system design step. To get a precise model of transmission line behavior above 1 GHz, geometry and material constants must ...

IETF 6TiSCH is emerging as a promised open-standard for industrial internet of things (IIoT). With employing Time Slotted Channel Hopping (TSCH) mode, 6TiSCH can meet critical requirements in the industrial sector such as reliability, determinism and ...

This paper presents a study and results from the effectiveness of the convolutional codes with code rate 1/2 and constrained lengths 7, 8 and 9. The dependencies of the bit error probability at the output of the Viterbi decoder from the generator ...

The increasing demand for mobile network capacity driven by Internet of Things (IoT) applications results in the need for understanding better the potential and limitations of 5G networks. Vertical application areas like smart mobility, energy networks, ...

In this paper, single layer multi-band reflective frequency selective surface (FSS) design is presented. Proposed design have stable frequency response up to 60 degrees of incidence angles. In the proposed hybrid design, three-armed geometry is placed ...

Ensuring a safe and environmentally friendly living environment requires the use of modern technological and engineering solutions to design and build high-risk facilities. Dangers to human health include the different electromagnetic fields emanating ...

Passive microwave imaging system are widely designed for the remote sensing, radio-astronomical observation and especially for the detection of weapons and contraband concealed on persons under clothing in the special control devices for public ...

Cluster systems bring with them many advantages of scalable parallel calculations. Many of these benefits are a result of the cost /performance ratio of large supercomputers. Other important aspects are related to the structure and method of ...

This paper presents a method for determining the relative permittivity of surface and sub-surface layers, such as a layer of snow on the ground and the hidden ground layers. In summer, the traditional two-ray model is expanded to three rays, where the ...

The total electron content TEC finds wide application in various scientific and technological areas. One of applications is the use of TEC to obtain critical frequencies foF2 of the ionosphere. The most studied is the situation in middle latitudes. High ...

The work addresses the Synthetic Aperture Radar (SAR) geometry, signal model and imaging process. Mathematical description of the observed surface is presented. A waveform with linear frequency modulation (LFM) reflected by the surface is used to ...

Context-driven systems provide information and/or services to the user and have specific features: a vaguely defined range of variables, contextual model, and context-sensitive services.

This paper is focused on coding the parameters of a hybrid genetic ...

Overcoming GPS signal disturbances is essential for achieving adequate vehicle navigation in urban environments. In a previous paper, we have proposed a top-down approach for modeling context-aware vehicle navigation systems. We have also proposed an ...

Currently mobile devices are of essential benefit for people in their personal and business activities. It is hence worthwhile maximizing those benefits and this in turn includes (among other things) minimizing corresponding health threatening effects ...
