Signal processing and telecommunications

Presentation

Random signals: random processes, stationary signals, correlation, ergodicity, covariance, spectral density.

Digital filters: Fast Fourier Transform, digital systems and signals, structure and properties of recursive and non-recursive filters, design methods and practical implementations.

Introduction to telecommunications: symbol and bit rates, transmission channels, multiplexing, baseband coding, modulations, spread spectrum, eye diagram, constellations, introduction to frames (signaling, synchronization…).

Organisation:

Lect. (28.75 h), Sem. (28.75 h), Lab (11 h), Evaluation (4 h).

Main difficulties for students:

Basic maths missing.

Objectives

At the end of this module, the student will have understood and be able to explain (main concepts):

• Definitions related to random signals
• Basis in spectral analysis
• Structure and design methods of digital filters
• Vocabulary and basic principles of telecommunication systems

The students will be able to devise a simple digital filter and to choose one communication protocol given application requirements

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
