Time-frequency characterization of harmonizable random processes
Hindberg, Heidi (Doctoral thesis; Doktorgradsavhandling, 2009)In this thesis we study how to characterize nonstationary harmonizable random processes simultaneously in time and frequency. Unlike stationary random processes, harmonizable processes can have a frequency content that changes with time. Rather than working directly with the process itself, we analyze the second-order moment functions of the process and characterize the process from these moments. ...
