In many fields such as telecommunications, multimedia, medical
technology, radar and sonar, man-machine communications, we utilize
advanced signal processing techniques to extrapolate underlying
information on specific problems for the purpose of decision making.
Traditional signal processing approaches assume the stationarity of
signals, which in practice is not often satisfied. Hence, time or
frequency descriptions alone are insufficient to provide comprehensive
information about such signals. On the contrary, time-frequency analysis
is more suitable for non-stationary signals. Therefore, this book
provides a status report of feature-based signal processing in the
time-frequency domain through an overview of recent contributions. The
feature considered here is energy concentration. The material covered in
this book should help shed some light on this exciting topic, and should
be especially useful to professionals in many fields dealing with the
analysis of non-stationary signals.
