At the end of this course the student shall have a working knowledge of digital communication systems, with focus on the modulation techniques and the quality of transmission. This covers a range of topics starting with random processes, going to baseband transmission and leading to modern wideband modulation techniques. The student shall have insight in the techniques (understand) and be able to quantify their properties (calculate).

Practical knowledge of a number of mathematical tools: random variables, trigonometric functions, complex numbers, phasors, Fourier-transforms. 
Basic knowledge of telecommunication principles, electronic circuits and system theory.


This course unit is a prerequisite for taking the following course units:
H05J6A : Modelling and Performance Analysis of Telecom Networks (No longer offered this academic year)
H09M0A : P&D Information Systems and Signal Processing
H0E91A : P&D ICT Security and Networks

This course is identical to the following courses:
H05B6A : Analyse van digitale communicatiesystemen

Study cost: 76-100 euros (The information about the study costs as stated here gives an indication and only represents the costs for purchasing new materials. There might be some electronic or second-hand copies available as well. You can use LIMO to check whether the textbook is available in the library. Any potential printing costs and optional course material are not included in this price.)

The slides used are available through the students organisation VTK. A handbook is referred to: Leon W. Couch, 'Analog and digital communication systems', Prentice Hall. Currently edition 7 is sold by VTK and in the Leuven bookshops, older editions can be used without difficulty.

This is a series of  nine two hour lectures, with interaction between students and teacher.

Problems are solved related to the following topics:
- random processes
- PSD of line codes and modulated transmissions
- ISI, bit-error rate and matched filter
- complex envelope and modulation techniques
- bit-error-rate

The reference material of the lectures is used. Exercises and solutions are provided during and after the sessions.

During the sessions the students work on problems and exercises with the help of a teaching assistance, and they have the opportunity to further discuss the material with their peers and the teaching assistent.

Evaluation

Evaluation: Analysis of Digital Communication Systems (B-KUL-H25A0a)

This is an open book exam.
What is allowed:
- course material= a print of the powerpoint slides (by VTK)
- the reference book= the book by Couch (Digital and analog communication systems)
