Teaching
I participate in the teaching of the following courses offered by the Department of Information and Communication Technologies at Universitat Pompeu Fabra.
Graduate Courses
Digital Communication Theory
Master in Advanced Sciences for Modern Telecommunications (joint Master program with Universitat de València)
The objective of this course is to get the student acquainted with advanced topics that are essential to the design and functioning of modern communication systems. In order to provide guiding themes, special emphasis is given to wireless networks and to digital subscriber lines. The topics covered include: review of band-pass and low-pass representation, channel modeling, channel capacity, energy per bit, advanced modulation techniques, fundamental bounds of error probability, intersymbol interference, linear equalization (ZF, MMSE), optimal sequence detection, capacity for parallel channels, SNR gap, Orthogonal Frequency Division Multiplexing (OFDM), bit loading, vector coding, block and convolutional codes, spread spectrum techniques for multiuser communications.
