Objectives
The aim is to provide students with knowledge on the SC (single Carrier) and MC (multi-carrier) modulations with Frequency Domain Equalization. This also includes the characterization of the transmitters and receivers suitable for high-rate wireless systems in presence of severely frequency selective channels. It is intended that the students become familiarized with the key aspects related with block transmission systems with frequency domain equalization as well as the characteristics of the iterative receivers. To achieve these goals the students must understand the effects of multipath and other error sources in the system performance and the techniques adopted to compensate them.
Finally systems based on SC and MC with frequency domain equalization, such as DVB, WIMAX or LTE, are studied.
The laboratorial component will provide students with a direct contact with simulation software that execute the subjects studied in the theoretical part.

Teaching method
The course consists on two weekly sessions of theoretical-pratical seminars with the duration of one hour and half each. There is also a laboratory part with one weekly session of two hours. In the laboratory the students must perform two group projects (two students per group).
Evaluation method
General Rule
The assessment is composed by a theoretical part and a laboratorial part.The student must have a minimum of 9.5 point in each part
The final grade for the approved students (in any of the possible dates of exams) is weighted in 75% for the theoretical part and 25% for the laboratorial part
Theoretical Part
The assessment of the theoretical part can be distributed or centralized:
Distributed assessment – consists on the execution of two mid-term tests. On the date of the final exam it is possible to repeat one mid-term test upon invitation from the structors. The theoretical grade is calculated using the following formula:
theor_grade = 37.5% 1st test + 37.5% 2nd test
Centralized assessment – consists on the execution of a final exam. In this case the theoretical grade is the grade of the exam. Students that opted by the distributed assessment can change to the centralized assessment any time during the semester.
