Course detail

# Data Communication

FEKT-BKC-DAKAcad. year: 2019/2020

Students will be introduced in detail to data transmission systems and the possibilities of realizing data communication. The course covers issues of information theory, information source and discrete communication system description. Furthermore, it focuses on data transmission, in particular on the basic concepts, data and signal description, transmission methods, transmission reliability, coding of analog and discrete signals. In greater detail it also focuses on coding: redundancy reducing code - prefix codes, the Huffman code, data compression principles. Forward error coding: Block codes, tree codes, turbo codes, concatenated codes, error security system. Last but not least, it also focuses on modulations, cryptography basics and other fields of data transmission.

Planned learning activities and teaching methods

Techning methods include lectures, computer laboratories, homeworks and practical laboratories. Course is taking advantage of e-learning (Moodle) system.

Assesment methods and criteria linked to learning outcomes

At the end of each laboratory or computer exercise the teacher checks the results of the given assignment and awards points. Assessment of computer exercises also includes assessment of homeworks. The points awarded for laboratory and computer exercises (a maximum of 30 points in a semester) go to the evaluation of the examination and thus also the assessment. The exam is written. The maximum number of points is 70. The overall evaluation is the sum of points for computer exercises, laboratories and a written exam. The minimum feasible value is 50 points; the maximum value is 100 points.
