In this paper we describe a noise reduction preprocessing algorithm for the adaptive multirate (AMR) speech codec of the GSM system. The algorithm is based on spectral weighting a...

— Given an unforced nonlinear system and two nested closed and invariant sets Γ ⊂ O, we present reduction principles allowing one to extrapolate the properties of stability, a...
