IMPROVED LOST FRAME RECOVERY TECHNIQUES FOR PARAMETRIC, LPC-BASED SPEECH CODING SYSTEMS |
摘要 |
A lost frame recovery technique for LPC-based systems employs interpolation of parameters from previous and subsequent good frames, selective attenuation o f frame energy when the energy of a subframe exceeds a threshold, and energy tapering in the presence of multiple successive lost frames.
