Iterative algorithm for signal reconstruction

Started by arnaud_trolle January 15, 2007
Hi everybody,

I was wondering a question about iterative procedures for signal
reconstruction from Fourier Transform Phase or Signed Fourier Transform
Magnitude (Oppenheim, Hayes, Van Hove): to your knowledge, can these
techniques apply to non-stationnary 1-D signals ? Or should I inevitably
go in for the use of iterative reconstruction from short-time Fourier
transform ?
In anycase, can anyone indicate me where I could find some algorithms
for these techniques freely on the web in a matlab code ?

Thanks for your help.
