Description of contents: programme

This course consists in advanced digital communications with a focus on the encoding and decoding techniques that allow us to approach the limits set by the information theory, and the analysis of these limits in the case of wireless communications, relating the physical characteristics of the channels and setting the receptors with the achievable transmission rate. The course will address at least the following content:
Finite-length information theory
Inference in Graphical Models
Advanced coding techniques: LDPC codes.
Design of LDPC codes over the Binary Erasure Channel
Decoding LDPC codes over General Channels
Synchronization Techniques and Channel Estimation

Learning activities and methodology

LEARNING ACTIVITIES AND METHODOLOGY
Three types of activities are used: lectures, seminars and practical projects. The assessment of these activities is complemented with two short written exams. Details on the evaluation and grading are given in next section.
LECTURES
Lectures are used to expose the major theoretical concepts, combined with exercises consisting of the design of illustrative algorithms. The instructor uses the blackboard (for mathematics) combined with specific audio-visual presentations for specific topics.
SEMINARS
The student will participate by solving different problems. In this way, the student can assimilate the concepts addressed in the lectures and self-assess his/her progress. The list of problems to be studied in each seminar will be available before hand.
We consider two types of problems:
There will be two types of problems to be studied in these sessions.
· "Closed problems": They are the classical problems and exercises with a clearly defined solution that the solutions should work out individually.
· "Open problems": They admit several solutions. They require that the students identify, formulate and propose solutions for several interacting subproblems. The students will tackle these problems working in teams. The teacher will collect some of these open problems for evaluation.
LABORATORY PROJECTS
Three projects are conducted during the course, related to the contents of LDPC coding and simulation of a simple MIMO channel.
Both projects are done in teams of two or three students. Include the design, simulation and measurement (using numerical software) of some of the algorithms in the lectures and problems. Each team delivers simulation code and a brief written report and make a brief presentation of the projects to the teacher and other students.
