Objectives
THE COURSE IS ORIENTED TO PROVIDE METHODOLOGICAL INSTRUMENTS FOR THE PROJECT AND ANALYSIS OF ANALOGUE AND DIGITAL COMMUNICATION SYSTEMS. THE COURSE PRESENTS, ALSO THE BASIC TECHNIQUES FOR ANALOGUE AND NUMERIC TRANSMISSION.
KNOWLEDGE AND UNDERSTANDING ABILITY
At the end of the course the student knows: methods for the analysis of analogical and digital modulation systems.
KNOWLEDGE AND UNDERSTANDING UNDERSTANDING
At the end of the course the student is able to: recognize and analyze the modulation scheme adopted, calculate the performances in the presence of white Gaussian additive noise.
JUDGMENT SKILLS Knowing how to identify the optimal modulation techniques in relation to the context.
COMMUNICATION SKILLS Knowing how to describe the acquired knowledge in a clear, concise and language-owned way.
LEARNING SKILLS Being able to apply the acquired knowledge to different contexts from those presented during the course, and to deepen the topics covered using materials other than those proposed.
Prerequisites
SIGNAL THEORY EXAM IS REQUIRED. MOREOVER, IT IS STRONGLY RECOMMENDED TO HAVE BASIC NOTIONS OF MATHEMATICAL ANALYSIS.
Contents
Introduction to electronic communication systems (3 hours of frontal teaching);
Fading models (4 hours of frontal teaching);
Amplitude modulations: AM, DSB, SSB, VSB (6 hours of frontal teaching, 2 hours of
classroom exercise);
PM and FM angle modulations. (6 hours of frontal teaching, 2 hours of classroom training);
Vector representation of signals. Signaling dimensionality, 2BT theorem, band of
Shannon. Maximum likelihood optimum receiver. Scheme of a minimum distance
and correlation receiver. (3 hours of frontal teaching);
Modulations: OOK, PSK, BPSK, QPSK, DPSK, FSK, BFSK. Calculation of error probabilities.
Union Bound. Modulations: PAM, PDM (PWM), PPM, QAM, PCM. Performance. (20 hours of
frontal teaching, 6 hours of classroom training);
Source entropy. Source and channel coding (outline). Intersymbolic interference and Nyquist criterion. (4 hours of frontal teaching);
Definition of estimator and properties. Fundamental Neyman-Pearson lemma. Likelihood ratio. Probability of false alarm and of detection. Receiver Operating Characteristic. (4 hours of frontal teaching).
Teaching Methods
HE TEACHING REQUIRES THE FREQUENCY REQUIREMENT. THE RULES FOR VERIFYING THE FREQUENCY OF THE COURSE WILL BE THROUGH THE ELECTRONIC REGISTRATION ( WITH THE BADGE) OF THE PRESENCES IN THE ROOMS WHERE THE BADGE READER IS PRESENT AND OPERATING OR THROUGH SPECIFIC PAPER REGISTER PROVIDED BY THE PROFESSOR. THE TEACHING PROVIDES THEORETICAL LESSONS (50 HOURS) AND CLASSROOM EXERCISES (10 HOURS).

Verification of learning
THE ACHIEVEMENT OF THE OBJECTIVES OF THE TEACHING IS CERTIFIED BY PASSING AN EXAMINATION (THE MINIMUM CORRESPONDS TO 18 AND THE MAXIMUM TO 30 CUM LAUDE). THE EVALUATION WILL THROUGH A WRITTEN TEST (AVERAGE DURATION OF 90 MINUTES) AND AN ORAL TEST (AVERAGE DURATION OF 40 MINUTES). THE EXAM WILL AIM TO CHECK
1) KNOWLEDGE AND UNDERSTANDING OF ARGUMENTS TREATED IN FRONTAL LESSONS;
2) THE EXPOSURE CAPACITY OF THE TOPICS;
3) AUTONOMY OF JUDGMENT IN PROPOSING THE MOST APPROPRIATE APPROACH TO ARGUMENT.
Sufficiency is required to pass the exam both in the WRITTEN verification (consisting of two numerical exercises) and in the ORAL one (consisting of a discussion on the written test and two / three theoretical questions).
The student reaches the sufficiency in the case of correct performance of an exercise of the written test and in case he proves to know the basic elements of the course in the oral one.
The student reaches the level of excellence if he / she correctly performs both the exercises of the written test and if he / she demonstrates, to the oral, the ability to make connections between the theoretical topics treated.
