"learning", "model". Ability to translate intuitive solutions constructed with such concepts into
concrete applications in different technological areas
Course Content
 Information and entropy: joint, conditional, and mutual.
 Relative measures, AEP and its consequences.
 Representation and codes: uniform, variable length, and adaptive.
KraftMcMillan Inequality and its consequences.
 Souce Coding and Compression algorithms
(Shannon, Arithmetic, Huffmann, Ziv and Lempel coding,
integer encoding, gamma and omega Elias coding)
 Basic concepts of channel coding, channel capacity.
 Basic concepts of modern Cryptography.
Learning Outcomes (Dublin Descriptors)
On successful completion of this course, the student should

understand and explain fundamental concepts such as entropy, mutual information, capacity,
compression, coding theorem, coding theory, coding and Cryptography;
compute entropy and mutual information of random variables;
formulate and prove The main theorems treated such as: i) AEP and its consequences,
ii) Optimality of Huffmann coding, and of arithmetical coding,
iii) the entropy is a lower bound for the expected length of a u.d block code,
iv) if P is different from NP then there exists no perfectly secret encryption scheme
with key shorter than the message.

understand and apply fundamental concepts in information theory such as probability,
entropy, information content and their interrelationships, AEP, data compression;
implement and analyze basic coding and compression algorithms;

be able to evaluate the aspects of information theory that can be applied in the real world. The student
should also be able to link the theoretical aspect of the discipline to the practical ones (such as
data compression)

explain how information theory and coding contributes to modern communications technology;
be able to describe the main results of information theory to other nonspecialist people
in the scientific community.

Be able to read and understand books and papers concerning the arguments treated in the course.
Solve advanced problems in the area.
Prerequisites and Learning Activities
Basic probability and discrete mathematics.
Ability to develop software applications.
Assessment Methods and Criteria
Written and oral.
