Title: Voice interval detector
Inventor: FUKUSHIMA MINORU
IPC: G10L15/04
Filed: 2003-11-25
Abstract: <P>PROBLEM TO BE SOLVED: To make a noise decision time constant regardless of the level of a reference signal.  <P>SOLUTION: In this voice interval detector, a background noise power estimation part 2 is composed of a filter having a response characteristic such that a rise time constant is relatively large and a fall time constant is relatively small. A time constant update part 4 adaptively updates the rise time constant of the background noise power estimation part 2 to have negative correlation with a instantaneous power estimated value Ps. Consequently, the rise time constant decreases as the level of the reference signal x(n) increases, and also increases as the level of the reference signal x(n) decreases, so a noise decision time Tn in which a decision part 3 detects a non-voice can be made shorter than the conventional noise decision time Tn' and constant, even when the level of the reference signal x(n) varies.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Each of the estimates is multiplied with a channel coefficient matrix that can be derived from communications of a known pilot signal, a product of each estimate obtained as a result and the channel coefficient matrix is subtracted from the received signal, and a corresponding differential is obtained as a result. Each corresponding differential can be multiplied with a filter weight vector. The received signal is decoded on the basis of the product of the differential obtained as a result and the filter weight vector. When the decoded signal is not matched to a predetermined interruption criterion, it is used for preparing an estimate for the following interference cancel.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
