Wireless Communications
Ing. Telecomunicazioni
/ Telecommunications Engineering
Laurea Magistrale, 1st semester
|
|
|
|
|
|
|
|
Wireless communication, which has peculiar characteristics with respect to
other physical media, is supposed to face three fundamental issues: limited
available frequency bandwidth, fading and signal dispersion phenomena and
interference generated by coexisting signals. The course treats these aspects,
the technological solutions for solving them, the multiple access systems and the
architectures of the current radio technologies.

Exam rules
|
|
The assessment is based on the following three components, generally completed
by an oral discussion:
1) a written exam on the theoretical part of the course with 3-4 questions,
which is the basis for evaluating how the fundamental concepts have been
assimilated and the capability of managing the theoretical tools. This part is
mandatory and it gives till to 21 points in the final score.
2) A written exam with 1-2 problems, which reflects the activity and the
solutions presented during the exercise hours in the course. This part is not mandatory. It gives till to
6 points in the final score.
3) A laboratory project, in Matlab, assigned by the teacher and developed,
also in a team,
according to the tools and solutions presented and discussed during the
laboratory hours in the course. This part is not mandatory and it gives till to
6 points in the final score. The project will be assigned around the
midsemester, before starting the laboratory hours or later, upon request of the
student.
The oral can be requested by the teacher in case of unclear points in the written exam and/or for discussing the laboratory project (if
present). An oral can be requested also by the student.
|
|
|
|
Option for the written exam in classroom (theory): closed-book or open-book (in this case the oral becomes mandatory). The exercises are open-book.
At the exam, you will be given two blank sheets (for the rough and fair copies)
and the exam text. The two sheets must be returned at the end of the exam.
|
|
|
|
In case of remote exams, the exam is open-book with mandatory oral.
|
|
|
|
|
|
Projects
|
|
The material for the laboratory project developed during the course is available
in the
WeBeep
portal. Some teams will be
formed during the laboratories. Who is not attending
the laboratories during the course can contact me for the project assignment and
the formation of new teams. Being part of a team is not mandatory.
The laboratories will be held in Nov. - Dec.
