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.
