ABSTRACT:
The conventional approach to infrastructure wireless networking employs a single antenna or single-user MIMO base station to transmit and receive information to and from multiple mobiles. Information flow is from a one to many and all links are effectively SISO in nature. In this talk we take a look at networks in which we deliberately deploy many more base stations than mobiles. Such networks are a branch of distributed MIMO networks: a topic of considerable interest in current wireless research. In this talk we describe the many advantages of coordinated distributed MIMO networks in the context of a simple proposed implemention. We show that challenging problems such as coordination of information, carrier and timing synchronisation and scalability of physical layer processing can largely be dealt with using techniques already applied in SISO wireless communications.

BIO:
Gerard Borg holds a joint appointment in the College of Physical Sciences and the College of Engineering and Computer Science. He has spent much of his career in plasma physics working on plasma fusion, wave-particle interactions in cold plasma and plasma antennas. Since 2000 he has worked in wireless concentrating on techniques for long-range broadband communications. He has promoted the BushLAN project to overcome the digital divide for regional and remote areas and has most recently made two submissions on wireless in-fill services relating to the NBN. In the CECS he offers courses in radiofrequency engineering and digital systems and microprocessors. He currently collaborates with ANU groups working on biosensors in the Research School of Chemistry and animal tracking with Fenner School.
