An Adaptive Anomaly Detector for Worm Detection
White Paper This paper presents an adaptive end-host anomaly detector where a supervised classifier trained as a traffic predictor is used to control a time-varying detection threshold. Training and testing it on real traffic traces collected from a number of... [11 Apr 2008]
Doubletalk Detection Using Real Time Recurrent Learning
White Paper The third detector determines the relative level of near-end speech vs.far-end echo in the microphone signal. The new double-talk detector combines information from all these detectors to make its decision. [19 Jul 2007]
A Modular Object Oriented Data Acquisition System for the Gravitational Wave AURIGA Experiment
White Paper The new Data Acquisition system for the gravitational wave detector AURIGA has been designed from the ground up in order to take advantage of hardware and software platforms that became available in recent years; namely, i386 computers running... [18 Apr 2007]
On the Design of Robust Multiband OFDM Ultra-Wideband Receivers
White Paper To combat efficiently strong NBI (with SIR less than 0 dB), this paper proposes a novel mixed interference suppression scheme that relies on the joint cooperation between a digital NBI detector and an adaptive analog notch filter. [13 Apr 2007]
Code-Aided Channel Tracking for OFDM
White Paper The channel estimator accepts information from the detector in the form of a posteriori probabilities. The estimator is robust in a sense that it makes very few assumptions regarding the underlying channel model. [11 Apr 2007]
Rotated Walsh-Hadamard Spreading With Robust Channel Estimation for a Coded MC-CDMA System
White Paper In a multiuser MC-CDMA system, possible performance improvements are based on the chosen detector, the channel code, and its Hamming distance. This paper investigates rotated Walsh-Hadamard spreading matrices for a broadband MC-CDMA system with... [16 Feb 2006]
