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.
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 smart-phone.
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.
5
Areas groups will work with
•
•
•
•
•
•
•
•
•
Algorithms (Matlab).
Project management.
Reports (Word or LaTeX)
Coding (Eclipse or emacs)
Web-pages.
Oral presentation (PowerPoint)
Setting up experiments, connecting cables.
Integrating.
Debugging, debugging, debugging.
Some will work with

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

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!

Cooperative localization
Teleconference with noise cancellation
Visual-based in-flight file-transfer
Wireless Ethernet tunnel (USRP project)
10
Project #1:Cooperative localization
•
Distances measured between
all nodes using sound pulses.
•
The information is sent to the
”master” through WiFi.
•
The position of the nodes
calculated by the master and
distributed to all nodes.
•
The results are presented on
the android screen.
