Valid for year : 2013
 
TSKS01 Digital Communication, 6 ECTS credits.
/Digital kommunikation/

For:   D   ELE   I   Ii   IT   SY   Y  

 

Prel. scheduled hours: 54
Rec. self-study hours: 106

  Area of Education: Technology

Main field of studies: Electrical Engineering

  Advancement level (G1, G2, A): A

Aim:
After passing the course, the student should
  • 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.
  • with experimental purpose be able to evaluate and to some extent implement such communication systems that are treated in the course.


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.
From Signals, information and communication: Channel models, baseband representation of narrowband signals, the entropy concept.

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 Continuation Course, 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:
  • Digital modulation: The vector model, ML detection, MAP detection, error probabilities, eye patterns, coherent and non-coherent detection. Common signal constellations, like FSK, PSK, QAM. Multi-dimensional signal constellations: OFDM.
  • 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. Kraftâ?Ts inequality.


Course literature:

Examination:
Written examination
Laboratory work
 5 ECTS
1 ECTS
 
The exam (TEN1) consists of two parts:
  • One introductory task that examines the course aims "be able to reliably perform standard calculations...". At least 1/2 of this task has to be solved correctly in order to pass the exam.
  • A problem and question part, examining the learning outcomes "be able to..."
The grade on the exam is based on the number of points obtained from the second part, provided that the first part is OK.
The laborations (LAB1) examines the course aim
  • with experimental purpose...
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 Swedish/English.
Department offering the course: ISY.
