Measurements in Communication Systems

Course Description

The basic measurement methods and instrumentation in communication systems are introduced with an emphasis on radio frequency and microwave measurements, propagation measurements and measurements of basic system parameters such as BER, EVM, constellation diagram, system throughput and similar. Particular emphasis of the course is on the practical work of students, which covers examples of measurements of basic parameters of circuits and systems in communications and electronics. Based on the theoretical and practical knowledge acquired, students will be able to measure all the basic measurement quantities that occur in everyday engineering practice in radio communications and electronics.

Learning Outcomes

  1. Identify basic measurement quantities in the radio frequency and microwave areas
  2. Explain the structure of standard laboratory instruments (power meter, signal generator, scalar and vector network analyzer)
  3. Select the appropriate measurement method and appropriate measurement instrumentation for each fundamental measurement in RF and microwave range (power, frequency, scatter parameters, spectrum, noise factor, EM field, antenna gain)
  4. Evaluate measurement error and its impact on interpretation of measurement results
  5. Explain the basic principles of measurement in system-level communications
  6. Select appropriate measurement method and appropriate measuring instrument for determining constellation diagram, EVM diagram, BER, throughput
  7. Explain the basic principles of measuring propagation aspects in communication systems
  8. Choose the appropriate measurement method and appropriate measuring instrument for determining diversity, system delays, scattering
