Spectrum Sensing (SS) plays an essential role in Cognitive Radio (CR) networks to
diagnose the availability of frequency resources. In this paper, we aim to provide an in-depth …

This manuscript presents a survey on new challenges in wireless communication systems
and discusses recent approaches to address some recently raised problems by the wireless …

As we advance towards 6G communication systems, the number of network devices
continues to increase resulting in spectrum scarcity. With the help of Spectrum Sensing (SS) …

Spectrum sensing (SS) is an essential task of the secondary user (SU) in a cognitive radio
system. SS monitors the primary user (PU) activity in order to avoid any collision with SU, as …

Damping is one of the critical factors in evaluating the performance of a structure under
loads resulting from winds, waves, and earthquakes. Due to significant uncertainties …

The current study aims at improving our common knowledge of precipitation and surface
temperature variabilities in Iran across different time scales (from intra-annual to decadal) by …

The problem of optimizing the topography of metal structures allowing Surface Enhanced
Raman Scattering (SERS) sensing is considered. We developed a model, which randomly …

This paper aims to assess the effective strain damage (ESD) model with a durability analysis
of an automobile coil spring under consideration of the load sequence effect. Conventional …

Laser shock peening (LSP) technology is commonly used to strengthen and extend the life
of components such as aero-engine compressor blades. Online monitoring of the LSP …

This study aims to assess the fatigue life analysis of strain signals with the implementation of
a reconstruction of the signals of the discrete wavelet transform (DWT) decomposition …
