📡 RF Engineer in progress | Link budget & propagation modelling | Satellite communications | DSP | SDR
📍 Zaragoza, Spain — open to national and international opportunities
Telecommunications technician transitioning into RF systems engineering. I build hands-on RF simulation projects to develop real engineering skills — currently focused on link budget analysis, propagation modelling and satellite communication scenarios.
Active learner, practical mindset, looking to contribute to real RF systems in space or critical communications.
Modular RF propagation and link budget toolkit — terrestrial and satellite scenarios. Implemented in Python.
Implemented:
- Propagation models: FSPL, Log-normal shadowing, Okumura-Hata, COST 231-Hata
- Link margin analysis and technology comparison (TETRA vs LTE)
- Satellite scenario: GEO at 35,786 km, S-band and UHF, atmospheric loss, elevation angle analysis
- LEO/VLEO dynamic pass simulation — orbital geometry, Doppler shift and Doppler rate, dynamic link margin, validated against STK Enterprise (AGI)
- Interactive Jupyter notebook demos with Plotly
In progress:
- Monte Carlo simulation for outage probability
- Electronic Warfare module
