Generalized area spectral efficiency: An effective performance metric for green wireless communications
(
IEEE
, 2014 , Article)
Area spectral efficiency (ASE) was introduced as a metric to quantify the spectral utilization efficiency of cellular systems. Unlike other performance metrics, ASE takes into account the spatial property of cellular ...
Wavelet Denoising Based on the MAP Estimation Using the BKF Prior With Application to Images and EEG Signals
(
IEEE
, 2013 , Article)
This paper presents a novel nonparametric Bayesian estimator for signal and image denoising in the wavelet domain. This approach uses a prior model of the wavelet coefficients designed to capture the sparseness of the ...
Opportunistic routing and data dissemination protocol for energy harvesting wireless sensor networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Recent advances in environmental sources harvesting technologies is a promising solution to provide sustainable energy sources for wireless sensor networks (WSN). Renewable energy sources such as solar, thermal and ...
Fault detection of infinite dimensional systems in presence of disturbances
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this brief paper we are concerned with the fault detection (FD) problem of single-input multi-output infinite dimensional (Inf-D) systems. We develop a geometric methodology to detect a fault in presence of a disturbance ...
Effects of Post and Early Selection on SEC Based Transmit Diversity Systems with Linear Power Loading
(
IEEE
, 2008 , Conference Paper)
Switch and examine combing (SEC) diversity scheme provides a lowest-complexity closed-loop transmit diversity solution. Furthermore, by probing sequentially available branches with different power loading levels, the SEC ...
Chip-Level Modulated BPPM Fiber-Optic Code Division Multiple Access
(
IEEE
, 2009 , Conference Paper)
Chip-Level Modulated Binary Pulse Position Modulation (CLM-BPPM) is proposed as a modulation scheme for Fiber-Optic Code Division Multiple Access (FO-CDMA) systems using Optical Orthogonal Code (OOC) for time domain signal ...
A comparison of quadratic TFDs for entropy based detection of components time supports in multicomponent nonstationary signal mixtures
(
IEEE
, 2013 , Conference Paper)
Separation of different signal components, produced by one or more sources, is a problem encountered in many signal processing applications. This paper proposes a fully automatic undetermined blind source separation method, ...
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 ...
Relay selection in underlay cognitive networks with fixed transmission power nodes
(
John Wiley & Sons, Ltd.
, 2013 , Article)
Underlay cognitive networks operate simultaneously with primary networks satisfying stringent interference constraints, which reduces their transmission power and coverage area. To reach remote destinations, secondary ...
A predictive strategy for lifetime maximization in selective relay networks
(
IEEE
, 2009 , Conference Paper)
Two algorithms based on an energy conserving dynamic transmit power threshold are proposed for improving the lifetime in relay networks utilizing selective relay strategies with amplify-and-forward (AF) relays. the lifetime ...
