Dr. Haidar Taki

Postdoctoral Research Fellow
School of Arts and Sciences – Natural Sciences

Haidar Taki was born in 1989. He received his master degree in “Signal, Telecom, Image, Parole” from the Lebanese University,  Faulty of Sciences (Beirut) in 2013. He also received the PhD degree in “High Speed Over Fiber Communications Utilizing Semi-Conductor Optical Amplifiers” from the Ecole Nationale d’Ingénieurs de Brest (France) in 2017, under the supervision of professor Stephane Azou. Currently, he occupies a postdoctoral research fellow position at the Lebanese American University (LAU).  His research interests include Ultra Wide Band communications and signal processing.  In particular, enhancing the quality of transmission for impulse radio systems via designing novel pulse shapes, advancing the existing data modulation patterns, smoothing the spectra of transmitted signals, besides to improving the bit error rate performance for transceivers based on coherent and non-coherent detection schemes, while considering additive white Gaussian noise (AWGN) channels and multi-path fading channels.
