EMI Protection of Communication Systems

Course Description

Parameters of the radiocommunication system. Possibility of jamming the wireless communication and devices and the interception of the radio traffic. Protection of false information in the radio traffic. Jamming. Cryptosecurity. Emission security from interception in communication systems. Physical security. Traffic-flow security. Transmission security in communication systems. Electrostatic discharge. Nuclear electromagnetic impulse and protection from it.

General Competencies

Acquiring the knowledge in protection of radiocommunication system from jamming and interception.

Learning Outcomes

  1. repeat parameters of communication systems
  2. explain electromagnetic properties of communication systems
  3. compute coupling between EM field and electronic equipment through apertures and via cables
  4. analyze guided and radiated interference
  5. design shielding of cables and communication equipment from EM fields
  6. evaluate measurement uncertainty of guided and radiated interference

Forms of Teaching


Lectrures are given with the use of powerpoint presentations published on the web pages. The lectures are organized through 2 cycles. The first cycle consists of 7 weeks of lectures and midterm, while other cycle has six weeks of lectures and final exam. The lectures are given in total of 15 weeks, two hours per week.


One midterm exam.


Consultation term is determined on the first lecture in agreement with the students.

Internship visits

One expert visit.

Grading Method

Continuous Assessment Exam
Type Threshold Percent of Grade Threshold Percent of Grade
Attendance 0 % 10 % 0 % 0 %
Mid Term Exam: Written 0 % 40 % 0 %
Final Exam: Written 0 % 40 %
Final Exam: Oral 10 %
Exam: Written 0 % 90 %
Exam: Oral 10 %

Students who have earned enough points to pass the exam do not have to take oral exam (they will get 0 points in that case).
