RESEARCH INTERESTS
-
Two-parameter wide sense stationary processes (linear
prediction theory, Wold decompositions, Gaussian-Markovian representation)
(1986-1991).
-
Linear system theory (lossless filters, connections
with interpolation of holomorphic matrix-valued functions).
-
Positive extension problems (covariance extension
under spectrum constraints, covariance extension in the periodically correlated
processes case).
-
Blind deconvolution of multivariable linear systems
and source separation.
-
Cyclostationary signal analysis.
-
Digital Communications: channel identification and
equalization, multi-user and multi-carrier communications systems,
non cooperative telecommunications.
-
Blind source separation of unknown digital communication signals.
-
Large random matrices and applications to
digital communications: performance evaluation of large CDMA, OFDM and MIMO systems, and evaluation of capacity achieving covariance matrices of
various MIMO systems.
