Research
Research serves as a cornerstone of the Center, and
is directed towards the study of advanced communications systems
employing advanced modulation, coding, and equalization techniques;
data transport, telemetry systems, and processing technology.
The Center has received extensive research grant support
from the National Aeronautics and Space Administration (Goddard
Space Flight Center and Glenn Research Center), the Department
of Defense (Air Force Office of Sponsored Researche and...),
and the National Science Foundation. |
