1.GOAL OF THE COURSE
Goal of this course is to describe the behaviour and evaluate the performance of the main components (e.g., functional blocks) constituting the analogue and digital communication systems and the packet-switched data networks.
2. Expected results
It is expected that the attending students will acquire the basic notions about architectures and related performance of both analogue and digital the TLC systems. A good underground of analogue and digital signal processing is demanded.
3. Required background
A good background on Signal Processing in the continuous-time and discrete-time domains is required.

The acquired skills would allow the student to be capable to carry out a basic performance analyisis of the point-to-point analog/digital communication systems that are affeted by noise and channel distorsions.

Courses of first two years in Information Engineering.
In particular, Signal Theory.

Communication system architectures : basic functionalities and services. [4h]
Analogue and digital communication systems : performance criteria. [4h]
Channel impairments and channel noise. [4h]
Transmit/receive architectures. [4h]
Analogue modulations ( AM and FM ) and Frequency Division Multiplexing ( FDM ) [4h]
A/D conversion ( PCM and DPCM) and Time Division Multiplexing ( TDM ) [4h]
Data traffic models, Statistical Multiplexing ( SM ) and basic notions of Queuing Theory [4h]
Line codes and spectral shaping. [2h]
Memory-less digital modulations ( OOK,PAM,QAM,PSK, FSK,PPM) and related differential formats. [6h]
Digital modulation with memory : CPM, CPFSK and GMSK. [6h]
Bandwidth and energy efficiency of digital modulation formats. [6h]

Lesson method: lessons in classroom
The requiring students are reiceved in presence.

The attention is recommended.
Four lessons per week

A single test in classooom of two hours of duration. The test is composed by five open questions. The maximum score of each open question is 6/30th. The test target is the evaluation of the skills acquired by the attending students.
