Training objectives
- The course provides fundamentals for the design and analysis of digital and analog communication systems.
The principal knowledge acquired regard signal filtering, modulation techniques, link budget, basis of antennas, characterization of noise and interference, wireless channel modeling, performance evaluation and tradeoff between costs and performance. Examples of design from significant applications are offered.
At the end of the course the student will be able to design wireless and wired communication systems, characterize signal-to-noise ratio and spectral efficiency, determine the performance and make a system design, apply knowledge in probability and statistics to the design and analysis of the transmission of random sequences of bits over random channels. Prerequisites
- Basic knowledge from
- the course Signals and Communications
- probability theory ad statistics. Course programme
- - Digital baseband systems
- Modulation and demodulation techniques (digital and analog)
- Digital passband systems
- Bandpass link
- Performance evaluation for digital and analog systems
- Trade-off performance vs. spectral efficiency
- Nonlinear effects
- Wireless channel
- Fading and countermeasures
- Introduction to multicarrier systems and coding
- Introduction to diversity techniques
- Introduction to localization systems
- Applications (design examples) Didactic methods
- The course consists in lessons from the instructor in class for all the arguments. For each argument theory will be followed by exercises. Additional exercises will be offered for individual study. An experimental activity in lab is also carried out.
The material for the students is available in English as well. Learning assessment procedures
- The examination is organized to allow the verification of knowledge learning with respect to the course program.
The examination consists in a written and in an oral part.
- The written part is related to an exercise with multiple questions regarding a simplified project of an analog or a digital communication system.
The kind of exercise is similar to those solved together with the instructor.
- The oral part consists of two questions spanning over the topics of the course.
The two parts are sustained in the same day, and the oral part can be accessed only if the written part is considered sufficient.
The final score accounts for both written and oral part.
The exam can be done in English.
The positive outcome of the examination shows the acquisition of knowledge and abilities specified in the course objectives. Reference texts
- Part of the material presented and that related to examples is provided by the instructor.
