The paper presents the design and processing-time evaluation of an embedded system with the purpose for forensic image detection based on the multi-resolution based algorithm. After the success of the proposed method we then successfully implement on the newest version of the hardware Raspberry Pi-3B which is currently a low cost and friendly environment for variously specific-research applications...
Spectrum sharing environment permits secondary users (SUs) to utilize radio spectrum of primary users (PUs) but creates cross-interference between SUs and PUs. Moreover, jamming signal is useful in improving information security by deliberately corrupting received signals at eavesdroppers. The current paper presents an analytical framework on communication reliability and information security, which...
This paper analyzes secrecy outage probability (SOP) of underlay cognitive radio systems (UCRSs) interfered by signals from primary networks, impaired by channel information inaccuracy and Rayleigh fading, constrained by peak transmit power and tolerable interference power. The analytical result is presented in an exact expression and corroborated by computer simulations. Multiple results illustrate...
Half-duplex energy harvesting (EH) amplify-and-forward (AF) two-way relaying (TWR) significantly improves spectral and energy efficiency, excellently satisfying stringent requirements of 5G (Fifth-Generation) mobile communication networks. The current paper proposes an outage probability analysis framework for such relaying over Nakagami-m fading channels. Toward this end, we first derive an exact...
We study underlay cognitive networks (UCNs) with maximum ratio combining (MRC) and opportunistic relay selection (ORS) under non-identical fading distributions, correlated signal-to-noise ratios (SNRs), and with direct link (DL) to fill in the literature gap which is limited to partially-identical fading distributions, uncorrelated SNRs, and no DL. To support performance evaluation, we propose asymptotic...
