A stable electronic interface circuit for sensing small inductances is discussed in this paper. the main application is for interfacing eddy current displacement sensors. the proposed circuit has been designed and implemented in a 0.35 μm BiCMOS process. the frequency oy the excitation signal is above 22 MHz, which eliminate. the skin effect oy the measurement result when using very thin targets. Oscillation stability issues along with an offset cancellation approach for the interface circuit are particularly taken into account. In this desig. the full-scale displacement range is 1.5 mm. Primary experimental results show that the signal to noise ratio is about 75 dB, with 240 μs measurement time and only 9.5 mW power dissipation. © 2009 IEEE.

Advances in PARAFAC Using Parallel Block Decomposition

16th International conference on Neural Information processing (ICONIP 2009)

Parallel factor analysis (PARAFAC) is a multi-way decomposition method which allows to find hidden factors from the raw tensor data with many potential applications in neuroscience, bioinformatics, chemometrics etc [1,2]. the Alternating Least Squares (ALS) algorithm can explain the raw tensor by a small number of rank-one tensors with a high fitness. However, for large scale data, due to necessity to compute Khatri-Rao products of long factors, and multiplication of large matrices, existing algorithms require high computational cost and large memory. Hence decomposition of large-scale tensor is still a challenging problem for PARAFAC. In this paper, we propose a new algorithm based on the ALS algorithm which computes Hadamard products and small matrices, instead of Khatri-Rao products. the new algorithm is able to process extremely large-scale tensor with billions of entries in parallel. Extensive experiments confirm the validity and high performance of the developed algorithm in comparison with other well-known algorithms.

Echo Energy Estimation in Active Sonar Using Fast Independent Component Analysis

In many underwater applications, it is desirable to separate independent signals according to their sources, allowing targets to be distinguished from self-noise, ambient noise and clutter. the long-term goal of this work is to better detect and model target echo under several location in real-ocean environments, and to develop signal processing techniques for echo energy estimation. this paper addresses echo energy estimation problem of active sonar in a set of sensors. this may be done by measuring a noiseless source signal echoed by a target whose acoustic properties are known. We propose an echo energy estimation method based on the following two stages;One is the blind source separation using an independent component analysis (ICA) to separate the remaining mixture into its independent components. We use the principal component analysis (PCA), as a preprocessor, to increase the input signal-to-noise ratio (SNR) of the succeeding ICA stage and to reduce the sensor dimensionality, and followed by the fast Fourier transform (FFT). As the second, after finding an original target echo signal, the energy estimation solution is newly proposed by considering an inverse procedure of the first stage, where the estimated sonar source is used as input for the pseudo-inverse procedure of the ICA filter combined with PCA. then, we can estimate noise-free energy information of a target echo, which is compared with conventional beam forming method. the real-ocean recorded data demonstrate the performance of the proposed algorithm.

Joint approximate diagonalization is one of well-known methods for solving independent component;analysis and blind source separation. It calculates an orthonormal separating matrix which diagonalizes many cumulant matrices of given observed signals as accurately as possible. It has been known that such diagonalization can be carried out efficiently by the Jacobi method, where the optimization for each pair of signals is repeated until the convergence of the whole separating matrix. the Jacobi method decides whether the optimization is actually applied to a given pair by a convergence decision condition. Generally, a fixed threshold is used as the condition. though a. sufficiently small threshold is desirable for the accuracy of results, the speed of convergence is quite slow if the threshold is too small. In this paper, we propose a new decision condition with an adaptive threshold for joint approximate diagonalization. the condition is theoretically derived by a model selection approach to a simple generative model of cumulants in the similar way as in Akaike information criterion. In consequence;the adaptive threshold is given as the current average of all the cumulants. Only if the expected reduction of the cumulants on each pair is larger than the adaptive threshold, the pair is actually optimized. Numerical results verify that the method can choose a suitable threshold for artificial data and image separation.

Optical steganography for data hiding in optical networks

Optical steganography for data hiding in optical networks

International conference on Digital signal processing (DSP)

作者： Paul R. Prucnal Mable P. Fok Konstantin Kravtsov Zhenxing Wang Department of Electrical Engineering Princeton University Princeton NJ USA

Optical steganography for data-hiding is experimentally demonstrated using group velocity dispersion in an optical network. A stealth channel is temporally and spectrally hidden underneath a public channel. Our technique applies to several different types of optical systems including optical code division and wavelength division multiplexing. the hidden signal is retrieved at the receiver through dispersion management. the effect of the stealth channel on the performance of the public channel is shown to be small; this is demonstrated through eye diagrams and bit-error rate measurements. To miniaturize the proposed scheme, compact chirped fiber Bragg gratings are used, reducing the length of the fiber providing group velocity dispersion is by a factor of 2000 compared to previous demonstrations.

We propose an efficient, deterministic algorithm designed to reconstruct images from real Radon-transform and attenuated Radon-transform data. Its input consists in a small family of recorded signals, each sampling the same composite photon or positron emission scene over a non-Gaussian, noisy channel. the reconstruction is performed by combining a novel numerical implementation of an analytical inversion formula and a novel signal processing technique, inspired by the work of Tao and Candes on code reconstruction. Our approach is proven to be optimal under a variety of realistic assumptions. We also indicate several medical imaging applications for which the new technology achieves high fidelity, even when dealing with real data subject to substantial non-Gaussian distortions.

International conference on Digital signal processing (DSP)

作者： Delaram Jarchi Bahador Makki Abadi Saeid Sanei Centre of Digital Signal Processing School of Engineering Cardiff University UK Electrical Engineering Department Islamic Azad University Ashtian Iran

In this paper a new method based on particle filtering for separating and tracking event related-potential (ERP) subcomponents in different trials is presented. the latency and amplitude of each ERP subcomponent is formulated in the state space model. Based on some knowledge about ERP subcomponents, a constraint on the state space variables is provided to prevent the generation of invalid particles and also make use of a small number of particles which are most effective especially in high dimensions. the method is applied on the simulated and real P300 data. the algorithm has the ability of tracking P300 subcomponents i.e. P3a and P3b, in single trials even in the low signal-to-noise ratio situations.

International conference on Digital signal processing (DSP)

作者： B.R. Matam David Lowe Aston University UK

We have recently proposed the framework of independent blind source separation as an advantageous approach to steganography. Amongst the several characteristics noted was a sensitivity to message reconstruction due to small perturbations in the sources. this characteristic is not common in most other approaches to steganography. In this paper we discuss how this sensitivity relates the joint diagonalisation inside the independent component approach, and reliance on exact knowledge of secret information, and how it can be used as an additional and inherent security mechanism against malicious attack to discovery of the hidden messages. the paper therefore provides an enhanced mechanism that can be used for e-document forensic analysis and can be applied to different dimensionality digital data media. In this paper we use a low dimensional example of biomedical time series as might occur in the electronic patient health record, where protection of the private patient information is paramount.

this paper reports a comparative study between two well-known identification engines, continuous hidden Markov model (CHMM) and artificial neural network (ANN) to identify the naval target. Mel frequency cepstral coefficients (MFCCs) are selected as the studied features. the general Gaussian density distribution HMM was developed for CHMM system. Elman network was developed for the ANN system. We studied the effect of speed, distance and direction of the target on the identification process. the results had shown that CHMM gives the best identification rate (IR) at 91.67% while changing range,100% while changing direction and 58.3% while changing the speed which is better than 75%, 83.33% and 41.67% of ANN for the same set of experiments using simulated targets data. Also, when using real target data CHMM achieves 100% IR which is higher than 73.68% of ANN.

LCD motion blur reduction using fir filter banks

LCD motion blur reduction using fir filter banks

引用

IEEE International conference on Image processing

作者： Shay Har-Noy Truong Q. Nguyen ViaSat Inc. USA ECE Department University of California San Diego USA

Due to the sample-and-hold nature of liquid crystal display (LCD) image formation, LCDs suffer from motion picture blur. this is especially evident during scenes containing fast motion due to the inherent sample-and-hold nature of LCD image formation. Using models for the human visual system (HVS) we take a signal processing approach to solving this problem by pre-processing the data before it is sent to the display. Whereas previous pre-processing approaches either apply a simple high pass filter or an iterative deconvolution algorithm, this work uses a small collection of efficient linear FIR filters to reduce the amount of perceived motion blur. Specifically, we develop a two-channel non-perfect reconstruction filter bank to reduce the motion dependent low pass effects of the HVS. Perceptual tests indicate that our algorithm reduces the amount of perceived motion blur on LCDs at a lower complexity than the existing deconvolution approach.
