Compact dual-band implantable antenna for e-health monitoring
(Institute of Electrical and Electronics Engineers, 2017)
This work presents a compact dual-band Planar Inverted F-antenna (PIFA) antenna useful for E-health monitoring and wireless sensors systems. The antenna operates in the Industrial Standard and Medical (ISM) and Wireless ...
A novel EBG structure to improve isolation in MIMO antenna
(Institute of Electrical and Electronics Engineers, 2017)
A new, and advanced Electromagnetic Band Gap (EBG) structure is reported to reduce the mutual coupling between two tightly spaced rectangular patch antennas. The EBG structure provides more than 20 dB reduction in mutual ...
Mutual coupling reduction in array elements using EBG structures
(Institute of Electrical and Electronics Engineers, 2017)
A 2D electromagnetic band gap (EBG) structure is designed on the ground plane of 1×2 rectangular patch antenna array to reduce the mutual coupling between the two elements and enhance the radiation pattern. An isolation ...
Enhancing the security performance of ostbc using pre-equalicodization
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, we first quantify the secrecy performance achieved by employing precoded orthogonal space time block coding (POSTBC) in order to use it as a benchmark for comparison purposes with a new proposed security ...
An efficient security method based on exploiting channel state information (CSI)
(Institute of Electrical and Electronics Engineers Inc., 2017)
A channel amplitude quantization method that can effectively quantize the channel response using just one single threshold value is proposed in order to extract a random manipulating sequence with good secrecy properties. ...
User association techniques in future heterogeneous networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
The exponential increase in the demand of data rate and scarcity of the available spectrum have evolved to the more advanced network topology which efficiently utilizes the radio spectrum such as Heterogeneous Networks ...

Prediction of infarct size using two-dimensional speckle tracking echocardiography in acute myocardial infarction
(Wiley, 2017)
Background: This study aimed to determine the myocardial damage (infarct size provided by cardiac single-photon emission tomography) in early stages of the infarction using longitudinal strain and rotational parameters of ...
