Sparse channel estimation for OFDM-based underwater acoustic systems in rician fading with a new OMP-MAP algorithm
(IEEE, 2019-03-15)
In this paper, a new channel estimation algorithm is proposed that exploits channel sparsity in the time domain for an orthogonal frequency division multiplexing (OFDM)-based underwater acoustical (UWA) communications ...
Site specific response analysis for performance based design earthquake characteristics
(Springer Science+Business Media, 2014-06)
During strong earthquakes, seismic waves travelling towards the ground surface alter the engineering characteristics of the soil layers and consequently the characteristics of travelling seismic waves also change with ...
On the feasibility of synchronous, retransmission-based cognitive networks
(Elsevier, 2016-01)
This paper presents a new, joint Markov chain model for the primary and secondary traffic in a cognitive radio network to assess the feasibility of opportunistic spectrum access for different operational scenarios, validated ...
MOO: An architectural framework for runtime optimization of multiple system objectives in embedded control software
(Elsevier, 2013-10)
Today's complex embedded systems function in varying operational conditions. The control software adapts several control variables to keep the operational state optimal with respect to multiple objectives. There exist ...
The likeability-success tradeoff: results of the 2nd annual human-agent automated negotiating agents competition
(IEEE, 2019)
We present the results of the 2nd Annual Human-Agent League of the Automated Negotiating Agent Competition. Building on the success of the previous year's results, a new challenge was issued that focused exploring the ...
An approach for detecting inconsistencies between behavioral models of the software architecture and the code
(IEEE, 2012)
In practice, inconsistencies between architectural documentation and the code might arise due to improper implementation of the architecture or the separate, uncontrolled evolution of the code. Several approaches have been ...
Enhanced MRC for decode-and-forward cooperative diversity systems
(IEEE, 2012-10)
In this letter, we propose a novel enhanced maximal-ratio combining (E-MRC) scheme for multi-branch decode-and-forward (DF) cooperative diversity systems consisting of a source, a destination, and multiple relays. This ...
Error probability of DF relaying with pilot-assisted channel estimation over time-varying fading channels
(IEEE, 2012-01)
In this paper, we investigate the error rate performance of a cooperative network with adaptive decode-and-forward (DF) relaying over time-selective frequency-flat Rayleigh-fading channels. We assume pilot-symbol-assisted ...
Eulogy to Professor Nicholas N. Ambraseys
(Springer Science+Business Media, 2013-02)
Sadly, at the final phase of all these preparations for Vol.11 N.1, our very dear and very distinguished Editorial Board Member Prof. Nicholas Ambraseys passed away on December 28, 2012 at the age of 83. Prof. Ambraseys ...
A custom-design atmospheric channel emulator for the performance evaluation of free space optical communication systems
(IEEE, 2017)
In this paper, we present our custom design atmospheric channel emulator for free space optical (FSO) system evaluations in a controlled environment. Our emulator is in the form of an atmospheric chamber with dimensions ...
