High Capacity Transmission
Objectives
At the end of this curricular unit the student will have acquired the knowledge, skills and competences that allow to:
- Know the physical limit of digital transmission of information
- Base-band and bandpass digital transmission techniques, including aspects such as spectral and power efficiency.
- Transmitter and receiver characterization for these types of signals, as well as appropriate signal processing algorithms.
- Channel codification techniques and coding/decoding algorithms.
- Become familiar with high capacity digital transmission techniques employed in modern digital communication systems
- Solid theoretical bases and abilities that allow a professional activity in the telecommunications area, or more advanced studies.

Teaching method
The theoretical part of the course is given in 2-hour classes, followed by 2-hour practical classes where application problems are solved.
Evaluation method
Presencial tests/exams
Students with special covid status make online tests
Online tests are different of presencial tests, have different duration and higher grades need to be defended.
The classification is defined by the arithmetic average of the tests or by the exam.
The students can repeat one test in the date of the exam.
