Rick Blum is serving as one of five guest editors

Rick Blum, professor of electrical and computer engineering, is serving
as one of five guest editors of a special issue of IEEE Transactions on
Signal Processing for Multiple-Input Multiple-Output (MIMO) Wireless
Communications Systems.

Transmit and receive antenna arrays used to form MIMO channels have
attracted interest because of the linear increase in capacity with the
number of antennas that they can provide. To achieve the potential in
practical systems requires yet-to-be-developed signal processing
solutions for efficient signaling, coding, and reception.  Blum says
fundamental innovations are needed on the theory of MIMO systems, their
performance and implementation, and in the careful control of their
complexity, which can easily become unmanageable.

Blum recently gave a talk on his research to members of The Technical
Cooperation Program (TTCP) meeting in New Jersey. TTCP is a group of
international technical experts from the U.S., Britain, Canada,
Australia and New Zealand who exchange technical and scientific
information and collaborate on defense-related research projects.
