Iterative blocking artefact reduction based on local contrast information
(
IEEE
, 2011 , Conference Paper)
Block based transform coding is the most popular
technique for image and video compression. However, images
compressed using block based algorithms exhibit highly visible
blocking artifacts. We propose an iterative ...
Joint interference cancellation and dirty paper coding for cognitive cellular networks
(2011 , Conference Paper)
Downlink communication in a cellular network with a cognitive (secondary) cell is considered. In our model, the base station of the cognitive cell knows the messages of the other cell non-causally. We propose a new ...
Advanced packet scheduling for efficient video support with limited channel feedback on MIMO LTE downlink
(
IEEE
, 2011 , Conference Paper)
Next-generation mobile networks will provide users with high data rates, increased mobility and various services. The initial step made in LTE and LTE-A is adopting the OFDM(A) air interface and utilization of dynamic ...
Accelerometer-based fetal movement detection
(
IEEE
, 2011 , Conference Paper)
Monitoring fetal wellbeing is a compelling problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity (movement), well-being, and later developmental outcome. We have recently ...
Time-frequency signal and image processing of non-stationary signals with application to the classification of newborn EEG abnormalities
(
IEEE
, 2011 , Conference Paper)
This paper presents an introduction to time-frequency (T-F) methods in signal processing, and a novel approach for EEG abnormalities detection and classification based on a combination of signal related features and image ...
Life cycle assessment of particulate recycled low density polyethylene and recycled polypropylene reinforced with talc and fiberglass
(
Trans Tech Publications Ltd
, 2011 , Conference Paper)
Although recycled polymers and reinforced polymer composites have been in use for many years there is little information available on their environmental impacts. The goal of the present study is to analyze the environmental ...
Time-Frequency Characterization of Tri-Axial Accelerometer Data for Fetal Movement Detection
(
IEEE
, 2011 , Conference Paper)
Monitoring fetal wellbeing is a significant problem in modern obstetrics. Clinicians have become increasingly aware of the link between fetal activity and its well-being. Using data acquired by accelerometry sensors, we ...
Analysis of cell spectral efficiency of infrastructure relay-enhanced cellular system
(
IEEE
, 2011 , Conference Paper)
In this paper, we investigate the downlink spectral efficiency of infrastructure relay-enhanced cellular systems. In particular, we use the average achieved spectral efficiency at an arbitrary mobile receiver in presence ...
Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
(
IEEE
, 2011 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the area of coverage. Therefore, it is ...
Exposure assessment to WiFi access points by simulations and measurements
(
IEEE
, 2011 , Conference Paper)
This paper discusses two different approaches to assess exposure to indoor WiFi access points at two different frequency bands: 2.4GHz and 5GHz. The first analyzes the electromagnetic propagation in almost empty environments ...
