FPGA Implementation of Orthogonal Matching Pursuit for Compressive Sensing Reconstruction
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we present a novel architecture based on field-programmable gate arrays (FPGAs) for the reconstruction of compressively sensed signal using the orthogonal matching pursuit (OMP) algorithm. We have analyzed ...
Efficient phase estimation for the classification of digitally phase modulated signals using the cross-WVD: A performance evaluation and comparison with the S-transform
(2012 , Article)
This article presents a novel algorithm based on the cross-Wigner-Ville Distribution (XWVD) for optimum phase estimation within the class of phase shift keying signals. The proposed method is a special case of the genera ...
Improving performance of deblocking techniques using image fusion
(2012 , Conference Paper)
Block based transform coding is the most popular technique for image and video compression. However, images compressed using block based algorithms exhibit blocking which is one of the most annoying artifacts in compressed ...
Signal content estimation based on the short-term time-frequency Rényi entropy of the S-method time-frequency distribution
(2012 , Conference Paper)
A key characteristic of a nonstationary signal, when analyzed in the time-frequency domain, is the signal complexity, quantified as the number of components in the signal. This paper describes a method for the estimation ...
Forced spectrum access termination probability analysis under restricted channel handoff
(2012 , Conference Paper)
Most existing works on cognitive radio networks assume that cognitive (or secondary) users are capable of switching/jumping to any available channel, regardless of the frequency gap between the target and the current ...
Handoff-aware cross-layer assisted multi-path TCP for proactive congestion control in mobile heterogeneous wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Multi-Path TCP (MPTCP) is a new evolution of TCP that enables a single MPTCP connection to use multiple TCP subflows transparently to applications. Each subflow runs independently allowing the connection to be maintained ...
Cloud of things for sensing as a service: sensing resource discovery and virtualization
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
We propose Cloud of Things for Sensing as a Service: a global architecture that scales up cloud computing by exploiting the global sensing resources of the highly dynamic and growing Internet of Things (IoT) to enable ...
Multi-stage intra-patient template matching for prostate detection in MR volumes
(2013 , Conference Paper)
Detecting objects, a significant task in computer vision, is accompanied with many challenges. When we focus on medical images, the challenges of detecting an organ or a tumour exhibit their own specific difficulties. ...
An Empirical Study for PCA- and LDA-Based Feature Reduction for Gas Identification
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
Increasing the number of sensors in a gas identification system generally improves its performance as this will add extra features for analysis. However, this affects the computational complexity, especially if the ...
