Lost frame concealment |
摘要 |
A receiver in a frame based radio communication system includes a speech decoder of the source-filter type which is controlled by internal state variables updated on a frame by frame basis for modifying received filter defining parameters representing background sounds transmitted over a communication channel. The receiver detects frame loss and conceals the effects of frame loss by restricting updating of at least one of the internal state variables. |
