Course Facts• Credits: 12.• Grade: ECTS. A-F.• Group work.• Number of students per group 3-7 (mostly 4-6).• You choose among a set of “eligible” projects.• You tell us about your skills.• We form groups and assign a leader.• One Project assistant per group.• Course responsible: Per Zetterberg.• Prototype responsible: You!• Goals and time-table are specified, how to achieve this
is up to the team.

Real-time based projects• Real-time processing on smart-phone or Ubuntu PC.• Receiving data from sensors (e.g. A/D converters)
transmitting data on actuators (e.g. D/A converters).• Presentation on of results on screen.• The signal processing in real-time is one of the major
challenges due to the resulting code/algorithm structure and computational-time constaints.
Group member roles:• Programmer .• Matlab/theory developer.• Group leader/generalist.

Smartphone/android based projects
• Display : plots and text.• Camera• Microphone.• Loudspeaker.• Magnetometer• Wifi RSSI measurements.• Send data using Wifi.• Acceloremeters.• Gyros.• Touch screen.
Features used in our projects:

USRP based projects• USRP = Universal Software Radio Peripheral• Used to transmit and receive wideband (4-8MHz) signals
over real radio transmitters and receivers.• Matlab interface to download and upload I&Q samples
for off-line development.• Real-time implementations are the goal.• The signals are distorted by real-world RF-impairments
(non-linearities, intersymbol-interference, phase-noise, frequency offset).

What would be your advice to a student who chooses this course next year ?• Don’t choose another course at the same period. Start really early with
everything.• Start working from the beginning• Work hard in the beginning and try to ease up in the end• Work hard in the beginning of the project• Start working from the first day, and don’t take more than a week off,
during the Easter• Choose it, but take it alone, with nothing else.• Work work work.• Take the course if you like to work hard.• Start early. Implement on DSP asap.• Don’t read other courses in parallel• Take it!
