   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multifönster; Tids-frekvensanalys; Instantaneous frequency; Multitaper; Signal resolution; Reassignment method; Time-frequency analysis;

   Sammanfattning : Spectral analysis encompasses several powerful signal processing methods. The papers in this thesis present methods for finding good spectral representations, and methods both for stationary and non-stationary signals are considered. LÄS MER

3. 2. Discrete Stochastic Time-Frequency Analysis and Cepstrum Estimation

   Författare :Johan Sandberg; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ambiguity domain; time-frequency analysis; time-frequency representations; covariance function; non-stationary random processes; Speaker recognition; MFCC; cepstrum;

   Sammanfattning : The theory of stochastic time-frequency analysis of non-stationary random processes has mostly been developed for processes in continuous time. In practice however, random processes are observed, processed, and interpreted at a finite set of time points. LÄS MER
