SEMINAR TITLE: Multi-Input Multi-Output (MIMO); Potential Applications – Myth and Reality ABSTRACT 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. BIOGRAPHY Dr. Mohsen Kavehrad , is the W. L. Weiss Professor of Electrical Engineering at The Pennsylvania State University . He received his Ph.D. degree in Electrical Engineering

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
