VERFAHREN UND EINRICHTUNG ZUR SPRACHKODIERUNG MIT NIEDRIGER DATENRATE. |
摘要 |
The encoding process comprises the steps of filtering voice signal using a short-term predictive filter tuned by sets of partial correlation related coefficients derived from s(n) and deriving from them a short-term residual r(n). A long-term residual e(n) is derived by subtracting a weighted and delayed synthesis short-term residual from the r(n). E(n) is split into consecutive blocks. Each block of the long term residual e(n) is code excited encoded into one TABLE address reference k and one gain G. |
