Position: R&D Physical Layer Engineer
Period: January 2010 – March 2013
During this period I collaborated in the next R&D projects:
DERFO 3DTV: led by Televes, the purpose of this project was to distribute 3DTV content over optical fiber and coaxial networks using the latest cable transmission scheme, DVB-C2. My principal tasks were the in-depth understanding of the DVB-C2 system, the SW implementation of the modulator and the HW design for the most time/memory consuming blocks. I also participated in the HW validation by providing test streams that previously were verified in the SW implementation.
The HW FPGA prototype was exhibited in the ANGA cable 2012 show.
EMULSION: with Egatel as client, this project developed the modulator and demodulator of a hybrid satellite-terrestrial digital communication system for mobile devices. DVB-SH and S-MIM were the selected technologies for the forward and return channel respectively. I was responsible of the SW simulations for the TU-6 multipath channel and the Return Link Encapsulation (RLE); and the VHDL programming of several blocks for the demodulator, such as FFT and coarse/fine frequency correction.
ONDADA: coordinated by Gradiant, the main objective in ONDADA was to increase the coverage of AIS (Automatic Identification System) in order that more vessels could use it. This technology allows ships exchange basic information such as speed and position with other ships and shore stations. My task was the study of the standard to help in the decision about which AIS repeater should be employed.
ANTICIPATION: with Broadcom as client, I was in charge of the fixed-point C implementation for the FFT radix-2 algorithm and the Viterbi decoder. These blocks were embedded on a SPARC LEON 3 architecture for a car communication system.
SARGO: research project in which the technical requirements (signal bandwidth, frequency band…) for several SAR (Synthetic Aperture Radar) applications were addressed. Among others, the applications under study were the anti-personnel mine detection and the human detection under foliage or in movement.
Other noteworthy developments during my period with the GPSC were:
• Holder of a Lucas Labrada grant sponsored by the Xunta de Galicia (2010-2011).
• DVB-T2 Seminar lecturer at Itelsis, Santiago de Compostela (Spain) on July, 14th and 15th 2011. A 10-hour seminar provided Itelsis R&D staff a suitable understanding of the DVB-T2 technology, from introductory concepts to laboratory test demonstrations.
• ASMS/SPSC 2012 attendee, held in Baiona (Spain) on September, 5th – 7th 2012.
• Participation in two European Space Agency projects: Ground based beamforming and S-UMTS.
