  1. ResearchActivities and ongoing work February 9th 2011 Mauro Biagi

  2. Outline • Introduction • Goals • Cognitive Radio • UltraWide Band Radio (UWB) • Visible Light Communications (VLC) • PowerLine Communications (PLC) • AcousticUnderwaterCommunications (AUC) • Information Theory and Secrecy • Resource Management forHeterogeneousNetworks • BiomedicalEngineering

  3. 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

  4. 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 Readyto Start Just Started Ongoing

  5. Cognitive Radio • The point in which wireless personal digitalassistants (PDAs) and the relatednetworks are sufficientlycomputationallyintelligentabout radio resources and relatedcomputer-to-computercommunicationstodetectusercommunicationsneedsas a functionofusecontext, and toprovide radio resources and wireless servicesmost appropriate tothoseneeds (J.Mitola III)

  6. Cognitive Radio • Mainactivities in thisframework are • SpectrumSensing • Cooperative detection • Spectrum Management • SpectrumSharing • SpectrumMobility

  7. Cognitive Radio Interest in: • SpectrumSensing Whenaccessoccurs Wigner-VilleTransformof a mono-dim. signal Image Processing (Edge Detection) Where

  8. Cognitive Radio Interest in: • Spectrum Management Primaryusershave a higherpriority withrespecttosecondaryones

  9. UltraWide Band (UWB) • Mainactivities in thisframework are • SymbolSynchronization • Multiple-Access

  10. UltraWide Band (UWB) Interest in: • SymbolSynchronization Training sequences can help synchronization whileturbo-scheme can reduce the number ofpulsesneededforSync.

  11. UltraWide Band (UWB) Interest in: • Multiple-Access The accessto the medium, UWB, isbased on the pulseshapethattakes care of masks, synchro and rate constraints

  12. Visible Light Comm’s (VLC) • Mainactivities in thisframework are • TX/RX Techniques • Channelmodeling • Device design Cooperationwith Boston University

  13. Visible Light Comm’s (VLC) • TX/RX Techinques

  14. Visible Light Comm’s (VLC) • TX/RX Techinques: Transmission rate vs. Reliability A “New” RAKE withdelay spread boundedto help rate

  15. PowerLineComm’s (PLC) • Mainactivities in thisframework are • InterferenceRejection • Spectrum Access • Routing • MIMO Schemes CooperationwithUniversityofBritish Columbia

  16. PowerLineComm’s (PLC) Interest in • InterferenceRejection • Delay Spread • Cross-Talk • ImpulseNoise

  17. PowerLineComm’s (PLC) Interest in • Spectrum Access ConventionalApproaches are not PLC-based

  18. PowerLineComm’s (PLC) Interest in • Routing

  19. PowerLineComm’s (PLC) Interest in • MIMO Schemes Spatial Multiplexing Interferencemitigation Powerconsumption

  20. AcousticUnderwaterComm’s • Mainactivities in thisframework are • ChannelEqualization and Coding • InterferenceSuppression • Spectrum Access CooperationwithRutgersUniversity

  21. AcousticUnderwaterComm’s Interest in: • ChannelEqualization and Coding

  22. AcousticUnderwaterComm’s Interest in: • InterferenceSuppression

  23. AcousticUnderwaterComm’s Interest in: • Multiple Access

  24. Inform. Theory and Secrecy • Mainactivities in thisframework are • To combat Eavesdropping • Toavoidmaliciousaccess

  25. Inform. Theory and Secrecy Interest in • To combat Eavesdropping In MIMO systemspowerallocation can aidsecrecy

  26. Resource management in HN • Mainactivities in thisframework are • Vertical Handover • Interoperability
