Data Communication MethodsLaajuus (6 ECTS)

Objective

After completing the course the student understands how data transmission quality and data rate depend on channel characteristics. He/she knows the most important physical layer transmission methods and understands why different methods are used in different conditions. He/she is able to estimate data rate achieved in certain conditions and which method is the most suitable for a certain application. With the help of this course the student is able to understand physical layer specifications of modern systems.

Content
