robust low bit rate codec - zhaohanwu - Sep 23 0:13:00 2005
I'm looking for a robust LP method in noisy environment (around 0dB),
which method can get better LP coefficient in harsh noisy background.
here is one method named "WLSP" proposed by Alku and Backstrom "All-
pole modeling technique based on the Weighted sum of the LSP
polynomials" in Proc. IEEE ICASSP'02 orlando, 2002. Have anyone test it?
i want use this method the extract robust LP coeff, so as to improve
the robustness of MELP algorithm. how about this idea?

How about first supress noise then compute LP?
