 It is advisable to have completed the courses "Fundamentals of Communications" and "Digital Signal Processing".

Objectives and Contextualisation

The course focuses on the study of access technologies, from the physical layer at the modulation level to the deployment of telecommunications networks at the infrastructure level. The objectives are:

  1. To understand the general principles of operation of these technologies.
  2. To design the corresponding schemes for transmission and reception.
  3. To comprehend the restrictions of each technology in terms of available resources, in order to design efficient systems.
  4. To know the basic characteristics of real systems, such as DVB-T/T2n, LTE or 5G
  5. To understand the real problems of installation, operation and maintenance of access networks
  6. To understand how is the spectrum managed
  7. To understand the standardization processes necessary to implement these networks


  • Apply deterministic and stochastic signal processing techniques to the design of communication subsystems and data analysis.
  • Apply the necessary legislation in the exercise of the telecommunications engineer’s profession and use the compulsory specifications, regulations and standards.
  • Communication
  • Design and dimension multiuser communication systems using the principles of communication theory under the restrictions imposed by the specifications and the need to provide a quality service.
  • Develop personal work habits.
  • Develop thinking habits.
  • Learn new methods and technologies, building on basic technological knowledge, to be able to adapt to new situations.
  • Work in a team.

Learning Outcomes

  1. Apply signal processing techniques in order to improve the features of multiuser systems.
  2. Assume and respect the role of the different members of a team, as well as the different levels of dependency in the team.
  3. Build, exploit and manage telecommunications networks from the point of view of access technologies.
  4. Communicate efficiently, orally and in writing, knowledge, results and skills, both professionally and to non-expert audiences.
  5. Develop critical thinking and reasoning.
  6. Develop independent learning strategies.
  7. Distinguish multiple access technologies based on digital signal processing techniques.
  8. Evaluate the advantages and disadvantages of different technological options for the deployment or implementation of emerging communication systems.
  9. Measure the features of different access technologies in terms of multiuser capacity.
  10. Prevent and solve problems.
  11. Use techniques based on telecommunication networks, services and applications both in fixed and mobile, and local or long distance environments with different bandwidths, including television and data.
  12. Work autonomously.

Final qualification will be based on the exercices and activities at class.

There will be around 5 exercises defining 80% of the qualification, and one class activity that will define 20% of the qualification. Active participation in class can rise the qualification up to one additional point.

Ater being qualified at least of 2 thirds of the total subject, the student will have the oportunity to have a final exam related to the whole subject. This exam will be after finishing the standard activities. In case the student does not attend this exam, won`t be a second chance.

In case of failing to present 2 thirds of the evaluation activities the sudent will be considered unqualifiable.

Honors are decided by the professor of the subject only if finla qualification is over 9.00 and no more than 5% of students can be awarded with this honors.
