Fast echo gain change detection |
| 摘要 |
An apparatus generally having a first circuit and a second circuit is disclosed. The first circuit may be configured to synthesize a first vector by filtering a second vector based on a third vector. The second circuit may be configured to (i) generate a gain corresponding to a fourth vector, (ii) compare the gain to a plurality of thresholds and (iii) update the third vector as a function of the gain where the compare determines that the gain is not between the thresholds. The fourth vector may be received from a network as an echo of the second vector. |

1. An apparatus comprising:
a first circuit configured to synthesize a first vector by filtering a second vector based on a third vector; and a second circuit configured to (i) generate a gain corresponding to a fourth vector, said fourth vector being received from a network as an echo of said second vector, (ii) compare said gain to a plurality of thresholds and (iii) update said third vector as a function of said gain where said compare determines that said gain is not between said thresholds. |
