Instantaneous Frequency Estimation of Multi-component Non-Stationary Signals using Multi-view Time-Frequency Distributions Based on the Adaptive Fractional Spectrogram
(
IEEE
, 2013 , Article)
This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS). A high resolution time frequency distribution ...
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 ...

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, ...
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 Model-driven Approach to the development of a PBL Script Editor
(
Global Chinese Conference on Computers in Education (GCCCE)
, 2013 , Article)
Designing a pedagogically sound and technically executable collaboration script is a highly complex,
time-consuming and error-prone task. This paper presents a model-driven approach to enable practitioners to design
online ...
Game-based micro-learning approach for language vocabulary acquisition using LingoSnacks
(
IEEE
, 2013 , Conference Paper)
Acquisition of new vocabulary is an important element for language learning but it requires repeated and varied exposure to the new words and their usage. This paper reports the experience of designing and developing a ...
Time frequency signal analysis and processing toolbox update 6.2: An enhanced research platform with new advanced high-resolution TFDs
(
IEEE
, 2013 , Conference Paper)
This paper describes the advancements, updates and improvements made in the new Time Frequency Signal Analysis TFSAP toolbox as compared with the previous TFSA toolbox version. The updates and improvements done in TFSA ...

(
IGI Global
, 2013 , Book chapter)
This chapter presents the findings of the first phase of a four-phase research study that involves the design and development of an integrated architecture for a mobile learning platform. During this phase, a high-level ...
Maximizing energy efficiency for loss tolerant applications: The packet buffering case
(
IEEE
, 2013 , Conference Paper)
Energy efficient communication has emerged as one of the key areas of research due to its impact on industry and environment. Any potential degree of freedom (DoF) available in the system should be exploited smartly to ...
