hours: 48
Rec. selfstudy hours: 112


Area of Education: Technology
Main field of studies: Electrical Engineering


Advancement level
(G1, G2, A): G2


Aim:
After passing the course, the student should
 be generally aquainted with classical telecommunication, i.e., be able to briefly describe different telecommunication techniques, and be able to briefly account for some simple channel models.
 be able to describe problems that arise in telecommunication situations using own words, and be able to describe and, in a relevant way, compare methods to counteract those problems in deterministic terms.
 be able to, with some precision, analyze analog modulation methods deterministically in spectral terms.
 be able to, with some precision, handle sampling and reconstruction of band limited signals deterministically.
 be able to, with some precision, compare various standard choices of digital modulation methods and coding methods in terms of error probabilities, minimum distance 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 simple telecommunication systems in block form and to empirically evaluate those systems.
 be able to analyze a given communication channel empirically, and suggest a communication system using that channel that fulfills given demands.


Prerequisites: (valid for students admitted to programmes within which the course is offered)
From Calculus: Derivatives, integrals and limits.
From Linear algebra: Everything related to linear spaces.
Statistics/probability theory is desireble, but not absolutely necessary.
Note: Admission requirements for nonprogramme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding.


Supplementary courses:
Wireless systems


Organisation:
The teaching is given in the form of lectures, problem classes and
laborations.
The course runs over the entire autumn semester.


Course contents:
 Simple channel models: Cables and radio channels, optical channels. Descriptions of the phenomena thermal noise and fading.
 Analog modulation in deterministic terms: AM, FM, PhM. Spectral properties, demodulation.
 Pulse modulation in deterministic terms: PAM, PWM, PPM, PCM. Sampling, modulation and reconstruction. Aliasing.
 Digital modulation: Common signal constellations, like FSK, PSK, QAM. Error probability expressions.
 Codes for error control: Binary symmetric channels. Binary linear codes, repetition codes, simple parity check codes, Hamming codes, product codes,cyclic codes and CRC codes. Basic parameters like length, dimension, size and minimum distance. Error detection and correction capabilities.
 Source coding: Tree codes, Huffman coding and runlength coding. Entropy, Kraft's inequality.
Note: Parts of this course can very well be somewhat simple for students with a thorough electrical engineering background, e.g., students on the programs Y, D and Is. A more reasonable choice in that case is TSKS01 Digital Communication. If that course is combined with TSDT14 Signal Theory, then that allows for more followup courses about communication.

Examination: 

Written examination Laboratory work 
4 ECTS 2 ECTS



The written exam (TEN1) consists of two parts, with minimum requirements in both parts for passing the exam. The first part is a a question part, where the course aims
 be generally aquainted with...
 be able to describe...
 be able to account for...
are examined. The second part is a problem part, where the course aims
 be able to, with some precision,...
are examined.
In the laborations (LAB1) the following course aims are examined:
 be able to implement...
 be able to analyze a given...
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.
