An apparatus for encoding a speech Signal using linear prediction for Algebraic Code excited in the autocorrelation domain

摘要

A device is disclosed for encoding a speech Signal by determining a Vector codebook algorithm of voice encoding.The Apparatus includes a determiner to determine a Matrix (110) autocorrelation Matrix R, and a determiner vector codebooks (120) to determine the Vector Code Book depending on the autocorrelation Matrix R.The determiner of matrices (110) is configured to determine the autocorrelation Matrix R by the determination coefficient vector a vector R, where the autocorrelation Matrix R comprises a Plurality of rows and a Plurality of columns, where the vector R indicates a Columns or rows of the autocorrelation Matrix R, where r (I,(j) = R (I, J | |) where r (I, j) indicates the coefficients of the autocorrelation Matrix R, where r is a Prime index that indicates one of a Plurality of rows of the autocorrelation Matrix R, and J is an index that indicates a second of the Plurality of columns The Matrix of autocorrel R ation.
