Najava predavanja: Steve Hranilovic "Communication Algorithms for Free-Space Optical and Optical Wireless Systems"

Sažetak predavanja:

Optical wireless links are an exciting compliment to RF systems for broadband content distribution both indoors and over longer ranges.  The availability of large amounts of unregulated bandwidth and immunity from RF interference are two primary advantages of optical wireless over radio systems.  For short-range indoor communications, optical wireless can operate in infrared or visible bands and provide large aggregate rates with high security.  Longer range free-space optical (FSO) links offer gigabit per second rates over several kilometers.  However, such systems are sensitive to atmospheric losses, turbulence and misalignment.  Only through careful system and signaling design can optical wireless systems approach their promised rates and reliability.

The primary focus of the seminar will be on the design of modulation, coding, channel topologies and MIMO techniques developed at the Free-Space Optical Communication Algorithms Laboratory (FOCAL) in McMaster University.  Key motivating applications of optical wireless and FSO channels will be also presented along with current and future experimental work.
