An echo canceller is configured to cancel an echo from an input signal using an adaptive filter. A double-talk detector provides a double-talk statistic. The double-talk statistic is proportional to the ratio of the remaining echo energy in the cancellation error signal and the total cancellation error energy. | 2010-06-03 |
20100135484 | HASH VALUE CALCULATION APPARATUS AND METHOD THEREOF - A hash value calculation apparatus, which calculates a hash value of a message, includes: an input unit adapted to input an extended block obtained from a message to be processed; a hash value calculation unit adapted to execute a hash value calculation of the input block and to output a hash intermediate value; a plurality of intermediate value storage units adapted to store the hash intermediate value output by the hash value calculation unit for the message to be processed; an output unit adapted to output a hash intermediate value associated with all blocks of the message to be processed as a hash value of the message; and a hash value calculation control unit adapted to control hash value calculations for a plurality of messages by switching the intermediate value storage units used to store the hash intermediate value output from the hash value calculation unit. | 2010-06-03 |
