S-72.232 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 counter­measures 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 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.

 

The lecture plan is here.

 

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 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 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
