Felix Albu, PhD
I have obtained the BSc degree in Electronics and the PhD degree in Telecommunications from Politehnica University of Bucharest in 1993 and 1999, respectively. I've worked as a teaching assistant at the same university from 1993 to 1999. During my PhD studies, I have been a visiting researcher for about two years at the National Institute of Telecommunications, Evry, France, and LAAS-CNRS, Toulouse, France. I've obtained extensive research experience as a postdoctoral researcher at University College Dublin, Ireland (1999-2002) and Aristotle University of Thessaloniki, Greece (2004-2005). Also, I've got industrial research experience at Lake Communications, Dublin, from 2002 to 2003 and at Fotonation Romania from 2006 to 2011. I've got the Dr. Habil. certificate in Electronics and Telecommunications in 2014. My Hirsch index is 34 according to Google Scholar, 27 according to Scopus, and 25 according to Web of Science. I'm listed in the world's top 2% of scientists for field-specific standardized citation indicators (2024, 2023, 2022, 2021). I'm an IEEE SPS Senior Member since 2013, and an Associate Editor of the IEEE Access since 2021. Currently, I'm a professor at the Valahia University of Targoviste, Romania.
I'm interested in collaboration opportunities in academic European/national research projects (contact me at felix.albu@valahia.ro). If interested in following a PhD program under my guidance in my area of interests, please send me an email.

Adaptive filtering for echo cancellation and hearing aids
---> I've proposed numerous affine projection algorithms (variants with variable step size, variable projection order, variable regularization, efficient implementations using Gauss-Seidel, DCD iterations, block-based, correntropy criterion-based, subband filters, proportionate versions, etc.). I've proposed RLS and NLMS type of algorithms for different applications (echo cancellation, noise reduction, adaptive feedback cancellation etc). To the best of our knowledge, we have published the first affine projection algorithm using the Gauss-Seidel in 2002 (link) or dichotomous coordinate descent (link) methods in 2005, the first division-less affine projection algorithm in 2003 (link), the first affine projection algorithm with a variable projection order (link) in 2003 and the first affine projection algorithm with two variable parameters (link) in 2011.

---> I’ve designed new imaging solutions for the digital photography industry used in digital image/video stabilization, low-light, panorama 2D/3D, and intelligent scene analysis. They were incorporated in digital still cameras and mobile phones. I have numerous granted US patents (US 7,773,118, US 8,155,468, US 7,995,855, US 8,204,330, US 8,212,882, US 8,208,746, US 8,351,726, US 8,199,222, US 8,493,459, US 8,493,460, US 8,587,665, US 8,587,666, US 8,508,652, US 8,649,627, US 8,649,628, US 8,698,924, US 8,705,894, US 8,737,766, US 8,989,516, US 9,160,897, 2 European patents (EP 2160715, EP 2149108) and one Romanian patent (RO 131754).

---> We've proposed numerous recursive least squares and affine projection-based algorithms for active noise control systems. They've included sparsity-aware approaches, the Gauss-Seidel, or Dichotomous Coordinate Descent methods.
Link to publications in the Active Noise Control area.
---> I've worked on the European High Speed Logarithmic Arithmetic (HSLA) research project. The world's first logarithmic microprocessor was designed, and I was involved in developing large signal-processing applications which were used both to prove the design at simulation and FPGA level (link). Some examples are here (useful Matlab and Handel C code). Link to publications in the Logarithmic Number Systems.
---> Voice activity detection: cepstral-based VAD, coherence-based VAD, soft VAD based on a Laplacian-Gaussian model, speech enhancement using spectral subtraction, and SVD. Link to publications in Speech Processing.
Neural Networks and Kernel Algorithms
---> I've extended the proportionate idea to kernel algorithms and proposed efficient implementations of various kernel-based algorithms. Link to kernel-based publications.
---> Several machine learning algorithms have been applied to various applications. Link to machine learning application publications.
