- Detta är en avhandling från Lund University / Centre for Mathematical Sciences /LTH
Sammanfattning : Non-stationary signals are very common in nature, e.g. sound waves such as human speech, bird song and music. It is usually meaningful to describe a signal in terms of time and frequency. LÄS MER
- Detta är en avhandling från Lund University
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
3. Estimation and Classification of Non-Stationary Processes : Applications in Time-Frequency AnalysisDetta är en avhandling från Centre for Mathematical Sciences, Lund University
Sammanfattning : This thesis deals with estimation and classification problems of non-stationary processes in a few special cases.In paper A and paper D we make strong assumptions about the observed signal, where a specific model is assumed and the parameters of the model are estimated. LÄS MER
