Patent ID: 7191136

Claim:
A system for efficiently coding signal information via predictors, said system comprising: a) a high-pass filter extracting high-frequency components of said signal; b) a low-pass filter extracting low-frequency components of said signal; c) linear and non-linear predictors used in modeling a parametric representation of said high frequency components of said signal, said high frequency component modeled as: X HFC ⁡ ( f ) = ∑ i = 1 N ⁢ ⁢ β i ⁢ X ′ LFC ⁡ ( f - M - i ) + R HFC ⁡ ( f ) , wherein, in case of said linear predictor, X′ LFC ( f )= X LFC ( f ) and in case of said non-linear predictor, X LFC ⁡ ( f ) = ∑ i = 1 N ⁢ ( X LFC ⁡ ( f ) * X LFC ⁡ ( f ) * … * X LFC ⁡ ( f ) ) j , and d) an encoder encoding said extracted low-frequency components and parameters associated with said linear and non-linear predictors.
