Project management for 5G RF basestation module solutions.

Macro-lead TX transmitters for 4G/5G cellular modem solutions: - Team control and support, definition and assignment of work packages - Definition of digital system blocks (feedback receiver, digital pre-distortion and envelope tracking) - Feature planning from digital hardware implementation to customer release - Alignment between system engineer (SE), firmware (FW) and system integration (SI) groups - Development of feature documentation and main customer technical contact

Research on enhanced power amplifier (PA) architectures: - Development of new adaptive digital predistortion (DPD) techniques - Development of new crest factor reduction (CFR) algorithms - Investigation and simulation of combined DPD and CFR architectures - Simulation of envelope tracking (ET) architectures - on-board RF PA measurements (linearity, gain, spurious generation,...)

Study of free-space optics laser communication thematics (atmosphere channel and optical telecommunication systems) and develop of a simulation software for satellite optical downlink communications. The focusing is on atmosphere turbulence and the noise sources in optical systems with some experiences in optical laboratory. The project was developed using the following software instruments: MATLAB and VPI Transmission Maker.

- Digital techniques to improve efficieny of mobile RF power amplifiers (DPD, CFR,ET) - On board RF Measurements (linearity, spurious, noise figure, mismatch, intermodulation....): - Behavioural modelling of RF systems (PAs, modulators, filters)

Telecommunication systems, coding techniques, radio propagation and antennas design, sensors and electronic system design
