Title of talk: Optical Wireless, Theory and Applications


Demands by the communications industry for greater and greater bandwidth push the capability of conventional wireless technology. Optical systems and networks offer a far greater bandwidth. This means new devices and systems have to be developed. Semiconductor Light Emitting Diode (LED) is considered to be the future primary lighting source for buildings, automobiles spacecraft and aircrafts. LED provides higher energy efficiency compared to incandescent and fluorescent light sources and it will play a major role in the global reduction of carbon dioxide emissions, as a consequence of the significant energy savings. Lasers are also under investigation for similar applications. These core devices have the potential to revolutionize how we use light, including not only for illumination, but as well; for communications, sensing, navigation, positioning, surveillance, and imaging.

This presentation covers the evolutionary path of the field.

Title of talk: Multi-Input Multi-Output (MIMO); Potential Applications – Myth and Reality


In its relatively short history, research on MIMO communications has reached to a high level of accomplishment with a very rich literature. The great success “STORY” of MIMO in RF communications has certainly motivated the desire of IEEE standards bodies to explore its capabilities in various forms of communications. As communications researchers rush to this potentially promising field, they tend to ignore the many unique properties and constraints of MIMO and start making wishful assumptions. Unfortunately, currently available results for RF communications cannot be applied to practical MIMO links that exhibit their own unique characteristics with underlying different statistical channel models and practical transmission techniques. This seminar is an effort to provide further insights into the performance of single-user MIMO links that ultimately are able to provide the largest achievable capacity, presenting the maximum diversity order achievable through the employment of multiple transmitter/receivers. We further discuss the effect of spatial correlation and demonstrate the necessity of enough transmitter separation and strict requirements to achieve the promised theoretical diversity advantages.

Furthermore, we offer examples where the MIMO payoff is not worth the additional hardware costs, today.
