Telecommunication systems work by using various kind of transmission channels whose properties inevitably dictate a great deal of system design. For instance, communication by microwave links, cellular mobile technology (wireless channel), Public Switched Telephone Network (PSTN), or by Power Line Communications (PLC), set a highly different requirements for telecommunication system design. The objective of this course is to inspect the various ways to deal with the challenging transmission channel in order to enable reliable and efficient telecommunications.

Course starts by inspecting properties of the most common communication channels (as for instance time-variable transfer function) and proceeds then to analyze the various modulation techniques. We consider first the analog approach that is then extended to digital telecommunications. Most telecommunication systems apply carrier wave modulation to convey information where an important component is system error performance. Application of coding plays an important part to maximize the transmitted information (source coding) and to reassure optimal reception (channel coding). We focus on understanding why, and how coding can be used to realize high-quality telecommunication systems. Considering the effects of noise, interference and limited bandwidth on modulated/coded transmission are also an important part of the course.

- 11.1.2005 Results of the exam on 21.12.2004 are here. To pass exam 14 points are needed. To get grade 5 from exam 40 points are needed. On the table you also see tutorial points (TGRADE) and Matlab points (MGRADE) and the Oodi results = course grades. OGRADE = ROUND(EGRADE+TGRADE+MGRADE). Remark that OGRADE can change when all Matlab exercises are graded (2nd deadline is on 21.1.2005).

- 22.12. Final results of Tutorial points are here!

- 15.12. Extra lecture notes added and Tutorial 11 solutions added (see below!).

- 10.12. All lecture slides (L1 - L11), totally 139 A4 pages, are available for copying. There are 11 envelopes containing slides (2 slides per A4 page) in a box on the table under courses noticeboard (on the corridor, near the E-wing). If needed please copy those papers as quick as possible - don't borrow those slides over a night! And don't mix the envelopes! REMARK! There are no handouts available from Edita concerning this course!

- 8.12. Example figures of Matlab exercises 1 - 10 are now available here: http://www.comlab.hut.fi/opetus/245/2004/matlab.html

- 1.12. Tutorial info has now been updated, see http://www.comlab.hut.fi/opetus/245/tutorialinfo.html

- 26.11. Example figures of Matlab exercises 1 - 4 are now available here: http://www.comlab.hut.fi/opetus/245/2004/matlab.html

- 4.11. What to read for exam? See page examinfo.pdf ver. 1 (page can be updated). All necessary formulas are given in exam paper so you not need to carry on rote learning!

- Lectures on Tuesday, 26.10.04 are cancelled.

- 21.10. Information about Matlab assignments is now added to the EeFORUM, see http://tltpc12.hut.fi/cgi-bin/mwf/board_show.pl?bid=16 Please write your question in English when using EeFORUM and remember that you can return all the assignments at the same time before the 1st exam!

- 5.10.2004 It seems that many students are lacking motivation in doing Matlab assignments. We have therefore decided that you can earn extra points by returning your Matlab exercises to the mailbox (2nd floor of E-wing) or to tutorials. This additional increase of your total course grade is at maximum 1/2. Example: If your exam grade is 2,3 and you have participated all tutorials and returned all related correct Matlab solutions your final grade would be 2,3 + 1 + 0,5 => grade = 4.

- 28.9.2004 Information about coming excursions is available here!

- Results and OODI-markings of the exam on 27.8.2004 can be found here

- 20.9.2004 Handout links added

- 9.9.2004 Information about tutorials is added.
