Northern Virginia Additions
The ECpE Northern Virginia program continues to expand with
the hiring of William J. Ebel and the transfer of A.
A. (Louis) Beex to the Alexandria
Research Institute. Both also teach graduate courses at the
Falls Church campus.
Ebel comes from Mississippi State University, where he was an
associate professor. He is an expert on the application of error
correction codes to wireless and wireline communications systems
with a special interest in implementation complexity. A recent
interest is the practical implementation of turbo codes with
particular interest on the finite wordlength effects. He also
works in algebraic coding theory and on the newly developed Space-Time
codes. He earned a Ph.D. from the University of Missouri-Rolla
in 1991.
Beex has spent 20 years at the Blacksburg campus and is the director
of the Digital Signal Processing Research Laboratory. His recent
work has involved noise cancellation and noise mitigation in
noisy environments; development of a computationally fast version
of the normalized least mean square algorithm with orthogonal
correction factors, and its applications to acoustic echo cancelation;
development of a time-varying autoregressive modeling approach
to interference cancellation; and software packages for voice-operated
email system simulation and low frequency audio processing.
