Introduction “Contamination” is not always bad!
“Contamination” may help especially if human (students, Ph.D. Students and professors) and/or between different disciplines
From this, the idea of a medium-short course of seminars
Goals Seminars are a good instrument for
scientific cooperation, testing speakers capability and help the ability to acquire criticism about the own work and the contributions of colleagues
Ready to Start Just Started Ongoing
Cognitive Radio The point in which wireless personal digital
assistants (PDAs) and the related networks are sufficiently computationally intelligent about radio resources and related computer-to-computer communications to detect user communications needs as a function of use context, and to provide radio resources and wireless services most appropriate to those needs (J.Mitola III)
Cognitive Radio Main activities in this framework are
Spectrum Sensing
Cooperative detection
Spectrum Management
Spectrum Sharing
Spectrum Mobility
Cognitive RadioInterest in:
Spectrum Sensing When access occurs
Where
Wigner-Ville Transform of a mono-dim. signal
Image Processing (Edge Detection)
Cognitive RadioInterest in:
Spectrum Management
Primary users have a higher prioritywith respect to secondary ones
UltraWide Band (UWB)Interest in:
Symbol Synchronization
Training sequences can help synchronizationwhile turbo-scheme can reduce the number of pulses needed for Sync.
UltraWide Band (UWB)Interest in:
Multiple-Access
The access to the medium, UWB, is based on the pulse shape that takes care of masks, synchro and rate constraints
Visible Light Comm’s (VLC)
Main activities in this framework are
TX/RX Techniques
Channel modeling
Device design
Cooperation with Boston University
Visible Light Comm’s (VLC)
TX/RX Techinques:
Transmission rate vs. Reliability
A “New” RAKE with delay spread bounded to help rate
