Multichannel acoustic echo cancellation is basically composed of two parts. One part is a multichannel system identification problem which is nontrivial to solve. The other part, which is also nontrivial, is the so-called double-talk detection problem. Near-end speech detection is based on a test statistic. Recently, a new double-talk test statistic based on the normalized cross-correlation vec...

The 2008 Workshop on Algorithms for Modern Massive Data Sets (MMDS 2008), sponsored by the NSF, DARPA, LinkedIn, and Yahoo!, was held last year at Stanford University, June 25–28, 2008. The goals of MMDS 2008 were (1) to explore novel techniques for modeling and analyzing massive, high-dimensional, and nonlinearly-structured scientific and internet data sets; and (2) to bring together computer ...

The existing theoretical approaches have been unable to confront the large corpus of outstanding data on the cuprate superconductor in a persuasive and unified manner. There is a general opinion now growing that these theories miss some essential points. We propose one based on multichannel Kondo effect that is physically justifiable and confronts the data adequately. In addition to earlier da...

System identification is the underlying mechanism of adaptive filtering algorithms in the context of acoustic echo cancelation systems. Multichannel system identification is subject to specific problems emerging from spatio-temporal couplings in the input signals of the adaptive filter. This paper presents a generic multichannel transformdomain adaptive filtering approach. It is based upon a tw...

When DVD and home theater systems become more popular these days, high fidelity multichannel (5.1 channel or 10.2 channel) audio systems are well received in the market. Compared with the traditional mono or stereo audio, multichannel audio requires a much more efficient coding scheme for its storage and transmission. This talk will present two new multichannel audio coding techniques: (i) the ...

Multichannel adaptive information systems can deliver services over different types of networks and access devices. Since different providers may offer either functionally equivalent or similar services, the quality of service (QoS) is a fundamental element of the service selection and the subsequent negotiation. This paper presents a taxonomy for quality dimensions, its application to differen...

A seismic method (e.g., surfaceor body-wave method) has been often used in pavement engineering to evaluate such critical constructional parameters as the E-modulus and Poisson’s ratio. Conventional method usually uses one or two-channel recording device (e.g., dynamic signal analyzer) for data acquisition whose cost is by no means trivial. In addition, recent applications with the multichannel...

The implementation of digital signal process system based on FPGA is an important method for embedded system. Pulse compression can be implemented in digital method. The realization of a multichannel pulse compression system by using all digital method has the characteristics of high reliability, strong anti-disturbance, good flexibility and convenient for application. In essence, pulse compres...
