Mutual radiation impedance of circular CMUTs on a cylinder
(IEEE, 2016)
In ultrasound imaging, cross coupling of transducer elements through the medium has significant effect on the frequency response, thus affecting the quality of the ultrasound image. In Side-Looking Intravascular Ultrasound ...
Sparse channel estimation and equalization for OFDM-based underwater cooperative systems with amplify-and-forward relaying
(IEEE, 2016-01-01)
This paper is concerned with a challenging problem of channel estimation and equalization for amplifyand- forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in sparse underwater ...
On the feasibility of synchronous, retransmission-based cognitive networks
(Elsevier, 2016-01)
This paper presents a new, joint Markov chain model for the primary and secondary traffic in a cognitive radio network to assess the feasibility of opportunistic spectrum access for different operational scenarios, validated ...
Analysis of asynchronous cognitive radio system with imperfect sensing and bursty primary user traffic
(Springer Science+Business Media, 2016-03)
This paper presents a theoretical analysis of the spectrum utilization levels in a cognitive radio system. We assume that the traffic of the primary network is bursty and asynchronous with the secondary network, which ...
MAC layer performance of the IEEE 802.15.7 visible light communication standard
(Wiley, 2016-05)
Visible light communications (VLC) is a high-speed wireless communication technology that has recently emerged. VLC uses the illumination infrastructure to meet broadband needs of bandwidth-hungry devices. Its high data ...
A tutorial on network coded cooperation
(IEEE, 2016)
Network Coding (NC) can significantly help increase the efficient use of network resources. However, directly applying NC to wireless networks is not an effective design solution. Wireless channels are prone to bit errors ...
Color filters: When “optimal” is not optimal
(IEEE, 2016)
It is well known that many more than three or four spectral measurements are required for accurate measurement of color. Previous work has shown seven to ten measurements can yield accurate results on average, but with ...
Cooperative visible light communications
(Springer Science+Business Media, 2016)
In this chapter, we explore the concept of cooperative transmissions in the context of visible light communications (VLC). An indoor office space is considered with two light sources; the one at the ceiling is connected ...
Serration effect on gain for microstrip E-Shape patch antenna
(IEEE, 2016)
In this work we focus on the effect of serration on E-Shape patch antennas. We simulated 2 different E-shape antennas with the same length. The first one has serrated edge and the second one doesn't have. Then we compared ...
Portable low cost ultrasound imaging system
(IEEE, 2016)
The applications of ultrasound in medicine have been increasing in the last decade either in diagnostics or in treatments. Ultrasound is routinely used in clinical examinations, such as pregnancy exams. On the other hand, ...
