Targets
The subject focuses on the study of access technologies, from the physical layer at modulation level to the deployment of telecommunications networks at infrastructure level. The objectives are:
Understand the general operating principles of these technologies.
Design the corresponding transmission and reception schemes.
Know the restrictions of each technology, in terms of available resources, and make efficient use of them.
Apply the knowledge acquired to real systems (classical or quantum).
Know the real problems in the implementation, operation and maintenance of access networks.
Understand how spectrum management is done.
Understand the standardization processes required to implement these networks.
skills
Apply the necessary legislation during the development of the telecommunications technical engineer profession and use the specifications, regulations and rules of mandatory compliance.
Apply deterministic and stochastic signal processing techniques in the design of communications subsystems and data analysis.
Learn new methods and technologies based on basic and technological knowledge, and have versatility to adapt to new situations.
communication
Design and dimension multi-user communications systems using the principles of communication theory under the restrictions imposed by the specifications and the need to provide quality of service.
Habits of thought.
Personal work habits
Teamwork
Learning outcomes
Apply signal processing techniques with the aim of improving the performance of multi-user systems.
Assume and respect the role of the various team members, as well as the different levels of team dependency.
Communicate efficiently, orally and in writing, knowledge, results and skills, both in professional environments and in front of non-expert audiences.
Build, exploit and manage telecommunications networks from an access technologies point of view
Develop independent learning strategies.
Develop critical thinking and reasoning.
Distinguish multiple access technologies based on digital signal processing techniques.
Measure the benefits of the different access technologies in terms of multi-user capacity.
Prevent and solve problems.
Work autonomously.
Use the techniques on which telecommunications networks, services and applications are based in both fixed and mobile environments, local or long distance, with different bandwidths, including television and data.
Evaluate the advantages and disadvantages of different technological alternatives for deploying or implementing emerging communications systems.
