About me

My name is Ridha Chaggara, and I was born in Jebeniana,Tunisia, in February 1976. I moved to France on september 1998, on June 2001 I received the Electronic Engineer Degree from the Ecole Nationale de l'Aviation Civile (ENAC) in Toulouse France and the Master's degree (DEA) from the INPT.
Fall 2004 I have obtained a PhD degree in satellite telecommunications and signal processing from the Enst Paris . The thesis was accomplished in the TeSA Loboratory in Toulouse with Marie-Laure Boucheret as supervisor.

Currently I'm involved as a system architect on EGNOS project which is the first major European GNSS (Global Navigation Satellite System) project. EGNOS is an augmentation system to GPS (Global positioning System) and aims at providing safe and reliable navigation for civil community.

Ph.D. Item

My PhD deals with Continuous Phase Modulations (CPM) and its application to future satellite communication in Ka Band.
The goal was to design an adaptive waveform based on serially coded CPM with iterative decoding process (Turbo like). Click here for more details or Download Thesis Dissertation.

Research Interests
