DEVICE AND METHOD FOR FRAME ERASURE CONCEALMENT IN A PCM CODEC INTEROPERABLE WITH THE ITU-T RECOMMENDATION G.711 |
摘要 |
<p>A device and method for resynchronization and recovery after frame erasure concealment of an encoded sound signal comprise decoding, in a current frame, a correctly received signal after the frame erasure. Frame erasure concealment is extended in the current frame using an erasure-concealed signal from a previous frame to produce an extended erasure-concealed signal. The extended erasure-concealed signal is correlated with the decoded signal in the current frame and the extended erasure- concealed signal is synchronized with the decoded signal in response to the correlation. A smooth transition is produced in the current frame from the synchronized extended erasure-concealed signal to the decoded signal.</p> |
