Description
Digital signal processing has become an essential part of
contemporary scientific and technological activity and even of everyday
life. The objectives of signal processing are analysis and diagnostics,
coding and compression, transmission and reconstruction.
Based on recent developments in harmonic analysis I will present some
new mathematical methods in digital signal processing.
In the first part of the talk I will discuss numerical algorithms for
reconstructing
signals from scattered data. Applications include medical imaging,
geophysics and music.
In the second part I will present some results on time-frequency
analysis of signals, a topic that plays an important role in
tele-communication and data compression.
