Biography

Chaima Elguet was born in Tunisia in 1990. She received the Dipl.Ing. degree in telecommunications from The Higher School of Communication of Tunis, Tunisia, in 2014, and the M.Sc. degree from the University of Québec (INRS-EMT), Montreal, Canada, under the advisement of Professor S. Affes in 2016. Her research works are mainly focused in the areas of wireless communication theory.(Based on document published on 17 March 2017).

Code-Aided DOA Estimation From Turbo-Coded QAM Transmissions: Analytical CRLBs and Maximum Likelihood Estimator

Faouzi Bellili;Chaima Elguet;Souheib Ben Amor;Sofiène Affes;Alex Stéphenne

IEEE Transactions on Wireless Communications
Year: 2017 | Volume: 16, Issue: 5 | Journal Article |
Cited by: Papers (9)
In this paper, we address the problem of direction of arrival (DOA) estimation from turbo-coded square-QAM-modulated transmissions. We devise a new code-aware direction finding concept, derived from maximum likelihood (ML) theory, wherein the soft information provided by the soft-input soft-output decoder, in the form of log-likelihood ratios, is exploited to assist the estimation process. At each...Show More

Code-Aided Direction Finding in Turbo-Coded Square-QAM Transmissions

Faouzi Bellili;Chaima Elguet;Souheib Ben Amor;Sofiene Affes

2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)
Year: 2015 | Conference Paper |
We investigate the problem of direction of arrival (DOA) estimation from turbo-coded square-QAM- modulated signals. We propose a new code-aided (CA) maximum likelihood (ML) direction finding technique that exploits the soft information obtained from the soft-input soft-output (SISO) decoder in the form of log-likelihood ratios (LLRs). Unlike standard estimation techniques, the proposed method impr...Show More

Closed-form Cramer-Rao lower bounds for DOA estimation from turbo-coded square-QAM-modulated transmissions

Faouzi Bellili;Chaima Elguet;Souheib Ben Amor;Sofiène Affes;Alex Stéphenne

2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Year: 2015 | Conference Paper |
Cited by: Papers (5)
This paper tackles the problem of the direction of arrival (DOA) estimation in turbo-coded systems. We derive for the first time the closed-form expressions for the Cramér-Rao lower bounds (CRLBs) of the code-aided (CA) DOA estimates from arbitrary square-QAM modulated signals. We succeed in factorizing the likelihood function of the system into two analogous terms linearizing thereby all the deri...Show More
