| Zusammenfassung: | A speech coder and a method for speech coding for optimizing computing efficiency in a speech compression process. The present invention increases computing efficiency in speech coders that perform conversions of linear predictive coding coefficients to reflection coefficients. Specifically, the invention removes a division operation from a recursive calculation within a the conversion process in a mixed excitation linear prediction decoder. As a result, less power is consumed and fewer clock cycles are required to run. |
