Modulation-independent non-data-aided SNR estimator for OFDM signals in nakagami fading channels
(2013 , Conference Paper)
A signal-to-noise ratio estimator for OFDM signals in Nakagami-m fading channels is proposed. This estimator can be used with any signal constellation. It is an envelope-based non-data-aided estimator that makes use of ...
Protecting private cloud located within public cloud
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
Many studies use cryptographic technologies to protect sensitive data in public cloud. However, these approaches may introduce large overheads. Recently, hybrid cloud started to gain a lot of attentions. A hybrid cloud ...
On the statistical distribution of electric field inside jet engines
(2013 , Conference Paper)
Using full wave analysis in 'Ansys HFSS', we obtain the electric field distribution inside a jet engine containing one set of 24 blades due to the excitation provided by a simple Hertzian dipole. Hertzian dipole illuminates ...
Impact of location heterogeneity on random walk mobility models
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
This paper investigates random walk mobility models with location heterogeneity, where different locations may have different neighboring regions.With the assumption of totally n locations, we consider two cases, i.e., ...
Copy limited flooding over opportunistic networks
(2013 , Conference Paper)
Mobile devices with local wireless interfaces can be organized into opportunistic networks which exploit communication opportunities arising from the movement of their users. With the proliferation and increasing capabilities ...
A survey on communication infrastructure for micro-grids
(2013 , Conference Paper)
A micro-grid is a small scale power supply network that is designed to provide electricity to a small community with its own renewable energy sources. Due to distributed generation variability, security and load sharing ...
Social interaction increases capacity of wireless networks
(2013 , Conference Paper)
A network model with both social and communication characteristics is considered. Different capacity regions are computed as a function of the social network size for each node. It has been shown that as the social ...
Taking advantage of multi-user diversity in OFDM systems
(2013 , Conference Paper)
A multi-user diversity approach, called Opportunistic Interference Management (OIM), is considered in connection with Orthogonal Frequency Division Multiplexing (OFDM) systems. The OIM is applied to each consecutive group ...
An improved real-time digital feedback control for grid-tie multilevel inverter
(
IEEE
, 2013 , Conference Paper)
This paper proposes a weighted Real-Time Digital Feedback Control for a grid connected Distributed Generation (DG) system (gas turbines, fuel cells, photovoltaic, wind.). The DG source is connected to the grid through a ...
Towards ultra high frequency and high efficiency gate drive circuits
(2013 , Conference Paper)
Recent developments in semiconductor technology enabled developing converters with ultra high switching frequency to achieve high power densities which increased the complexity of designing optimized gate drive circuits. ...
