Method and device for frame error detection |
摘要 |
A frame error detection method includes the steps of determining a plurality of comparison values which include a given comparison value depending on a frame energy of a given speech frame or a change in frame energy between the given speech frame and a preceding speech frame. The given speech frame is identified as a bad speech frame if a logical combination of a plurality of criteria is met. One of the criteria is based on a comparison of a threshold value with the given comparison value depending on the frame energy or the change in frame energy. A device for frame error detection and a receiver including the device for frame error detection are also provided.
