Good understanding of communication systems with deeper insight of particular phenomena from the electromagnetic waves propagation theory, processing of stochastic signals, evaluation of modulation methods and signal detection. Theoretical basic comprehension of physical system phenomena, not reducing the system knowledge only on general block view.
- 1. Introduction with the basic terms of mobile communications along with the special emphasis on wireless interface. Student is gaining knowledge of all phenomenons that are affecting on the quality of the transmission of information with the radio channel.
- 2. Student can apply the knowledge from the theory of electromagnetic waves on understanding of the phenomenons inside of the radio channel and connect them with the technical solutions of certain mobile systems towards quality assurance for all levels of services.
- 3. Knowledge of mobile communications basics prior has application in further process of learning and solving particular examples.
- 4. Students can, based on the knowledge of channel response in time or frequency domain, analyse behaviour of the system for certain type of information which is transferred through the channel. It means that based on impulse response you can conclude whether it is about narrowband or broadband channel.
- 5. Because it is a elementary course, which gives an overview of the phenomenons, it isn't estimated that the students can be able to suggest some plan for solving the particular problems.
- 6.With the acquirement from the course student can reach cognition about solvability or unsolvability of particular problems in mobile communications.
Forms of Teaching
Lectures are held with the help of a power-point presentation with explanations on the blackboard. Lectures are available in electronic format on the course website.Exams
The assessment is carried out through two written exams (one mid-term and final exam) and final oral examination.Exercises
Numerical examples are an integral part of the course.Experimental Exercises
During the course are provided three demonstration exercises. At the end of each exercise, test activities carried out, checking understanding of the material presented.Consultations
Permanent consultation entire whole semester.Other
During the semester, one homewor is provided with concrete numerical problems from the course.Other Forms of Group and Self Study
During the semester several projects are planned from the course topics. Intention is to solve complex tasks, often with the use of computers and software simulations. Each project would be dealt with smaller groups of students.
