Purpose:
To explore and understand the technologies of modern software
defined radio (SDR) communications. Software radios are emerging
very rapidly in commercial and military infrastructure. This rapid
growth is motivated by the many advantages SDR offers. These
coupled with the increasing computational power available from
commercially inexpensive digital signal processing devices makes
the future so that SDR will become the standard method used for
radio design. The challenge of an SDR is a broad range of knowledge
required, including digital signal processing algorithms, RF
circuits, software methodologies and SDR-related environments as
communication channels and antennas.
Generally, this course covers basic SDR knowledge through short
theory lessons followed by simulation exercises and small projects
carried out in hardware platforms.
Non-technical skills:
- Being able to extract knowledge into worksheets.
- Collect information and acquire new knowledge.
- Communicate technical problems in writing and orally.
- Cooperate in groups.
Læringsmål:
En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:
Discuss strengths and, weaknesses of an SDR compared with a
conventional radio.
Explain the purpose of the individual blocks in a digital
radio.
Analyse communication channel effects, including: link budget,
range equation, noise temperature and interferences.
Explain the basic concepts of decimation and
interpolation.
Describe the basic principles for SDR modulation types and
explain their differences and similarities.
Create a simple model covering basic SDR modulation forms in
Matlab.
Apply multi-rate processing algorithms on a hardware
platform.
Synthesize waveforms using direct digital synthesis (DDS) in
Matlab and explain structure of apply-able hardware
algorithms.
Describe basic blocks in A/D and D/A converters and identify
their limitations.
Kursusindhold:
- Design and simulate fundamental SDR radio blocks.
- Analyze communication channel effects on a SDR.
- Analyze and design basic antennas.
- Build and use Matlab simulation tools to support the learning
process.

Bemærkninger:
Course will run at DTU Ballerup Campus but if the students at DTU
Lyngby Campus are interested there will be lessons online via adobe
connect and you need to physical presented 4 times in semester for
the practical exercises.
In the beginning of the semester, the students form groups. The
group-size should be 3-5 students. In special cases, the teacher
can accept smaller groups. Each group will have a supervisor to
support their project-work and carry out the exam.
Exam: Oral examination is based on a presentation of the worksheets
prepared during the course. They form basis for a discussion of the
reached results and solution of the problems. The problems are
announced during at the beginning of the course.
