Prerequisites
The Course exploits and deepens concepts acquired in the Course of ”Telecommunications”

Learning outcomes
Know and understand the themes of "Telecommunications" in more detail, both in terms of theoretical characterization and of possible applications.

Program
- Binary sequences: generation through LFSR and chaotic algorithms. - Optimal receiver in the presense of thermal noise and bandwidth limitations (hard detection). - Continuous phase modulations. - Equalization techniques for the multipath channel. - Viterbi's Algorithm with hard decision. - Pragmatic approach to block and convolutional codes for error correction. - Examples of turbo codes and their use in teh TLC standards. - Spread spectrum techniques. - Outline of ultra-wide bandwidth systems. - Channel capacity. - Introduction to cryptography. - Software tools for simulating communication systems.

Development of the examination
LEARNING EVALUATION METHODS
The exam consists of an oral test. If necessary, the questions requiring the execution of short calculations are answered in written form during the oral test.

LEARNING EVALUATION CRITERIA
In order to pass the exam, the student must demonstrate to possess an adequate knowledge of the course's contents, and to be able to expose them in a sufficiently correct way and by using the right technical notation. The maximum score will be reached by showing a deep and thorough knowledge of the topics, and a complete control of the related technical concepts.

LEARNING MEASUREMENT CRITERIA
The learning level will be measured by the student's capacity to demonstrate his knowledge of the topics, their importance and applicability in frameworks of practical interest. Based on the learning level shown by the student, the teacher will assign him a score expressed in thirtieths.

FINAL MARK ALLOCATION CRITERIA
The oral exam consists of two or three questions, depending on the topics discussed during the interview. Each answer receives a score ranging between 0 and 15 (for the case of two questions) or between 0 and 10 (for the case of three questions). Laude is assigned to those students who, having reached the maximum score, demonstrate a thorough knowledge of the subjects. In assigning the final score, the teacher also takes account student's participation to software exercises developed during the course, with certified attendance through signatures collection. In any case, proof of attendance of the software exercises will not compensate a negative evaluation of the oral test, but will eventually contribute to improve the positive evaluation.
