The Signal Processing in Communications Group (GPSC) has been consistently developing two parallel research lines which make extensive use of advanced signal processing tools. On one side, we have experience in the application of such techniques in communication systems and sensor networks, e.g., in synchronization, equalization, link monitoring and adaptation, satellite and mmWave communications, spectrum sensing, etc. On the other hand, the group has been active in the field of multimedia security, including digital watermarking, digital forensics, and signal processing in the encrypted domain. The proficiency of the group can be seen by the results obtained in these areas: in the last 10 years, GPSC members have directed 9 PhD theses, published over 70 papers in international journals, and secured €9M in funding from public (including European projects) as well as private sources (with more than 10 patents).
