Replacement: S-72.135 Fixed Radio

Communication Systems Networks <=> S-72.3210 Channel
Modeling for Radio Communication Systems 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 CommuÂniÂcaÂtion
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 I in the academic year 2006 – 2007
starting at September 19. Tuesdays 12
– 14, I346; Wednesday 12
– 14, E110; 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://www.comlab.hut.fi/opetus/3210/) and
on the informaÂtion board on
floor E3. Teacher: Professor Sven-Gustav
Häggman (lectures and exercises). Requirements: The
course is carried out by an exam. The exam requireÂments consist of the
material distributed to the students. There will be two exams: the first exam
is on October 31, 2006. 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
As professor Häggman will retire from November 1, 2006, it is
strongly recommended that the exam is done at the first occasion --------------------------------------------------------
