S-72.3220 Radio Communication Systems
Course targets:
The course gives basic knowledge about basic propagation mechanisms, radio channel modeling principles, average path loss vs. distance models, fading types, channel parameter statistics, LTV channel representation and important channel models.
Course motivation:
The radio channel has a crucial impact on the transmission of information through it. In almost all applications multipath propagation will occur during a significant part of the time. This time dispersivity causes a frequency selective behavior of the channel transfer function, and without countermeasures harmful intersymbol interference is generated. Movements in the transmission medium and especially the movement of the transmitting or receiving station cause Doppler-shifts.
This frequency dispersivity causes time selective behavior of the received signal level, signal fading. This requires that the operation of counterÂmeasures must adapt to the actual channel situation. Frequency and time selectivity can also be utilized for better performance and higher capacity In order to design proper radio link budgets or to rollout radio network nodes in a cost effective way the radio communication engineer must know which propagation mechanisms are important in different applications, and how they build up the received signals.
As the phenomena are random channel models for the linear time-variant radio channel are required to estimate the performance of radio links and radio networks. For effective fading countermeasures channel estimation is necessary
Prerequisites:
The course
S-72.1140 Transmission Methods in Communication Systems
S-72.1110 Signals and Systems
or their equivalents are assumed to be acquired before this course.
Lectures and exercises:
These are held weekly at the following times in Period II in the academic year 2007 - 2008 starting at November 1.
Tuesdays 12 - 14, I346;
Wednesday 12 - 14, I346;
Thursdays 12 - 14, I346
In the exercises demonstrative problems and solving methods are presented.
In each exercise two home works are given, which should be returned for checking and grading.
The scores will have an impact on the final course grade.

Assignment:
There are no compulsory assignment but it's possible that teacher gives extra homeworks for "bonus points".
Information:
Possible changes are announced on the course homepage (http://tll.tkk.fi/fi/Studies/S-72.3210) and on the information board on floor E3.
Teacher:
Professor Sven-Gustav Häggman (lectures and exercises).
Literature:
Lecture notes (are available from Edita). See more information about literature here!
Requirements:
The course is carried out by an exam. The exam requirements consist of the material distributed to the students. There will be two exams: the first exam is on December 17, 2007.
This is an open-book exam, where the use of arbitrary source material is allowed except for team work between the students or other persons. Use of scientific calculators is usually required.
The student must pass the exam. Please use Topi to registrate for the exam!
Final grade:
The final course grade is calculated from the formula:
Final grade = Texam + 0.2Texercises
(The student must pass the exam. )
