A Multi-Channel Acoustic Echo Canceller Double-Talk Detector Based on a Normalized Cross-Correlation Matrix
White Paper Multi-channel acoustic echo cancellation is basically composed of two parts. Recently, a new double-talk test statistic based on the normalized cross-correlation vector was proposed for the single-channel case. [03 Jul 2008]
XAP 400
White Paper The XAP 400 features Gentner's proprietary Distributed Echo Cancellation® and noise cancellation technology for dramatically reduced echo and noise; a proven software architecture for easy, reliable configuration; a matrix with level control at... [03 Jul 2008]
A Frequency-Domain Double-Talk Detector Based on Normalized Cross-Correlation Vector
White Paper Furthermore, assuming that the adaptive algorithm of the echo canceler is a frequency-domain formulation, the complexity of the DTD is low since many of the computations can be re-used. This paper presents a frequency-domain calculation scheme for... [03 Jul 2008]
2.5 MHz 2D Array with Z-Axis Backing
White Paper Measurements are presented on the electrical impedance, directivity and cross talk of the 2D array module, as well as the pulse echo properties of the 2D array elements exited through the Pad Grid Array interconnect system. [14 Aug 2003]

Privacy scandal: Dodgy data laws on the way
News The latest proposals echo a report from the UK's National Criminal Intelligence Service (NCIS) last August, which caused a storm of protest at the time. The plans date back to 1995 when Europe adopted a cross-Atlantic interception agreement with... [17 May 2001]
