    摘要: A voice decoder configured to receive a sequence of frames, each of the frames having voice parameters. The voice decoder includes a speech generator that generates speech from the voice parameters. A frame erasure concealment module is configured to reconstruct the voice parameters for a frame erasure in the sequence of frames from the voice parameters in one of the previous frames and the voice parameters in one of the subsequent frames.

    摘要: Systems and methods for adapting a de-jitter buffer to conform to air link conditions. An air link characteristic may be detected before that characteristic begins to affect packet delivery, such as by slowing or speeding delivery delay at a subscriber station. A receiver-side de-jitter buffer, which adds delay to received packets, may adaptively adjust its size based upon the detected air link characteristic, such that the de-jitter buffer is appropriately sized for anticipated data packets before they are received at the subscriber station.
