Aim:
After passing the course, the student should
- be able to briefly account for some common channel models, especially for cables, radio channels and optical channels.
- be able to describe problems that arise in communication situations, using own words, and be able to describe, and in a relevant way, compare methods to counteract those problems.
- be able to reliably perform standard calculations regarding digital modulation, binary (linear) codes for error control and source coding.
- be able to, with some precision, analyze and compare various choices of digital modulation methods and coding methods in terms of error probabilities, minimum distances and related concepts.
- be able to account for the connection between different concepts in the course in a structured way using adequate terminology.
- be able to implement such communication systems that are treated in the course in block form and empirically evaluate them.

Prerequisites: (valid for students admitted to programmes within which the course is offered)
From Calculus: Foremost integrals.
From Linear algebra: Everything related to linear spaces.
From Signals and systems: Fourier transforms, convolution, LTI systems.
.
Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding.
|

Supplementary courses:
Digital communication Advanced, Wireless systems, Radio communication, Error correcting codes, Source coding, Image and audio coding.
|
|
Organisation:
Teaching is given as lectures and problem classes.
The course runs over the entire autumn semester.
|
|
Course contents:
- Channel models: Cables, radio channels and optical fibers.
Thermal noise, fading and intersymbol interference.
- Digital modulation: The vector model, ML detection, estimation, error probabilities. Common signal constellations, like FSK, PSK, QAM.
- Multi-dimensional signal constellations: OFDM.
- Representation of signals: Complex baseband representation
of deterministic passband signals.
- Signal-theoretic basics: Auto-correlation and power spectral
density.
- Codes for error control: Binary symmetric channels. Binary linear codes, repetition codes, simple parity check codes, Hamming codes, dual codes, product codes, cyclic codes and CRC codes. The sphere packing bound and the Singleton bound. Basic parameters like length, dimension, size and minimum distance. Weight and distance distributions. Error detection and correction capabilities.
- Source coding: Tree codes, Huffman coding and run-length coding. Entropy, Kraftâ?Ts inequality.

The exam (TEN1) consists of three parts:
-
One introductory task that examines the course aims
"be able to reliably perform standard calculations...".
This task has to be solved correctly in order to pass the exam.
-
A question part, with questions of descriptive or investigative
character. This part examines the learning outcomes
"be generally aquainted with...",
"be able to briefly account for...",
"be able to describe problems..."
and
"be able to account for the connectionâ?¦".
Separate demands on the number of points in this part to pass.
-
A problem part, that examines the course aim
"be able to, with some precision, analyze and compare...".
Separate demands on the number of points in this part to pass.
The grade on the exam is based on the total number of points obtained.
The laborations (LAB1) examines the course aim
The grade of the course is given when both parts are passed,
and the grade is the same as that of the written exam.
The written exam can be replaced by oral examination in the event of very few students having signed up for an exam. |
Course language is English.
