Computer Engineering MA, Wireless Communication, 6 credits

Aim

The course provides basic knowledge about problems and methods for construction of radio communication systems. The main emphasis is on digital radio systems. In particular it is illustrated how different forms of signal processing is used for the construction of efficient radio communication systems.

Course objectives

After completion of the course, students should
- Perform link budget calculations in connection to the design of wireless communication links.
- Identify and describe various physical and statistical fading channel models.
- Present modulation techniques for wireless communication and their spectral properties as well as evaluate their performance over fading channels.
- Give an account for coding techniques, which can be used for improvement of the transmission reliability.
- Describe and solve problems about direct sequence and frequency hopping band spreading techniques.
- Analyse and describe properties for various diversity methods,
- Present and use the basic principles for design and analysis of wireless cellular systems.
- Give an account and solve problems about ARQ and some basic multiple access techniques.

Grading criteria for the subject can be found at www.miun.se/gradingcriteria.

The examiner has the right to offer alternative examination arrangements to students who have been granted the right to special support by Mid Sweden University’s disabilities adviser.

If examination on campus cannot be conducted according to decision by the vice-chancellor, or whom he delegated the right to, the following applies: Written Exam T103, will be replaced with two parts, online examination and follow-up. Within three weeks of the online examination, a selection of students will be contacted and asked questions regarding the examination. The follow-up consists of questions concerning the execution of the on-line exam and the answers that the student have submitted.

Grading system

Seven-grade scale, A, B, C, D, E, Fx and F. Fx and F represent fail levels.
