Gaussian Source Detection and Spatial Spectral Estimation Using a Coprime sensor array with the Min Processor

Gaussian Source Detection and Spatial Spectral Estimation Us...

引用

作者： Liu, Yang Buck, John R. Electrical and Computer Engineering Department University of Massachusetts Dartmouth DartmouthMA02747 United States

A coprime sensor array (CSA) interleaves two undersampled uniform linear arrays with coprime undersampling factors and has recently found broad applications in signal detection and estimation. CSAs commonly use the product processor by multiplying the scanned responses of two colinear subarrays to estimate the spatial power spectral density (PSD) of the received signal. This paper proposes a new CSA processor, the CSAmin processor, which chooses the minimum between the two CSA subarray periodograms at each bearing to estimate the spatial PSD. The proposed CSAmin processor resolves the CSA subarray spatial aliasing equally well as the product processor. For an extended aperture CSA, the CSAmin reduces the peak sidelobe height and total sidelobe area over the product processor for the same CSA geometry. Moreover, unlike the PSD estimate from the product processor, the PSD estimate from the CSAmin is guaranteed to be positive semidefinite. This paper derives the probability density function, the complementary cumulative distribution function (CCDF, or tail distribution), and the first two moments of the CSAmin PSD estimator in closed form for Gaussian sources in white Gaussian noise. Numerical simulations verify the derived CSAmin statistics and demonstrate that the CSAmin improves the performance over the product processor in detecting narrowband Gaussian sources in the presence of loud interferers and noise. The CSAmin spatial PSD estimate achieves lower variance than the product processor estimate, and keeps the PSD estimate unbiased for white Gaussian processes and asymptotically unbiased for nonwhite Gaussian processes. © 2017 ieee.

In this paper, we derive two robustness properties for the set-membership normalized least-mean-square (SM-NLMS) algorithm. The first property provides local bounds for the error/discrepancy in the coefficient vector at a given iteration, whereas the second property expands the previous one for any given iteration. As a result, this paper demonstrates for the first time that the SM-NLMS algorithm is robust (1 2 -stable), no matter how the algorithm parameters are set.

2nd International workshop on Information processing in sensor Networks

One task in which inaccurate measurements are often used is location discovery, a process where the nodes in a network determine their locations. We have focused on location discovery as the primary target of our study since many sensor network tasks are dependent on location information. We demonstrate the benefits of location error analysis for system software and applications in wireless sensor networks. The technical highlight of our work is a statistically validated parameterized model of location errors that can be used to evaluate the impact of a location discovery algorithm on subsequent tasks. We prove that the distribution of location error can be approximated with a family of Weibull distributions. Then, we show that while performing the location discovery task, the nodes in a network can estimate the parameters of the distribution. Finally, we describe how applications can use the estimated statistical parameters to: (i) estimate the confidence intervals for their results, (h) organize resource consumption to achieve optimal results in presence of estimated magnitude of error.

2nd International workshop on Information processing in sensor Networks

We address the problem of deterministic oversampling of bandlimited sensor fields in a distributed communication-constrained processing environment, where it is desired for a central intelligent unit to reconstruct the sensor field to maximum pointwise accuracy. We show, using a dither-based sampling scheme, that is is possible to accomplish this using minimal inter-sensor communication with the aid of a multitude of low-precision sensors. Furthermore, we show the feasibility of having a flexible tradeoff between the average oversampling rate and the Analog to Digital (A/D) quantization precision per sensor sample with respect to achieving exponential accuracy in the number of bits per Nyquist-period, thereby exposing a key underpinning "Conservation of bits" principle. That is, we can distribute the bit budget per Nyquist-period along the amplitude-axis (precision of A/D converter) and space (or time or space-time) using oversampling in an almost arbitrary discrete-valued manner, while retaining the same reconstruction error decay profile. Interestingly this oversampling is possible in a highly localized communication setting, with only nearest-neighbor communication, making it very attractive for dense sensor networks operating under stringent inter-node communication constraints. Finally we show how our scheme incorporates security as a by-product due to the presence of an underlying dither signal which can be used as a natural encryption device for security. The choice of the dither function enhances the security of the network.

Many researches have proved the significance of gait analysis since it strongly relates to several urgent health issues. As a response, we develop an unobtrusive sensor device, named SennoGait, which provides comprehensive gait information. In this paper, we verify the robustness and reliability of the device's hardware components, including a 16 pressure sensors array and a 9-axis inertial measurement unit with state-of-the-art tools.

Detection of DVB-T2 control symbols in passive radar systems

Detection of DVB-T2 control symbols in passive radar systems

sensor array and multichannel signal processing workshop

作者： Keijo Pölönen Visa Koivunen SMARAD CoE Department of Signal Processing and Acoustics Aalto University School of Electrical Engineering Aalto Finland

Passive radars offer several advantages over the conventional radar systems by using a source of illumination that is independent from the receivers and primarily used in other purposes. The second generation digital television standard DVB-T2 is a good alternative to be utilized as an illuminating system. Passive radar receivers should be able to detect the target echo at very low signal-to-noise ratios. In this paper, a novel detection method for the DVB-T2 signal is proposed that fulfills these conditions. Distributions of test statistic are established and the performance of the method is verified with simulations. It is shown that the proposed method is suitable for passive radar systems and can be used without the exact knowledge of the transmitted signal waveform.

This paper introduces a graph signal processing (GSP) framework for industrial process monitoring. Through a graph built to represent the variables of an industrial plant and their relationships, we show how to transform each sample vector observation using the graph Fourier transform (GFT) in order to infer the status of the plant. To validate the proposed method we compare it to the state of the art PCA T 2 and Q methods for the Tennessee Eastman Process (TEP), a widely used benchmark for validation of methods in control and process monitoring. The results show our method outperforms PCA in most cases.

ieee Digital signal processing workshop

作者： V. Cevher J.H. McClellan Georgia Institute of Technology Atlanta GA Georgia Institute of Technology Atlanta Atlanta GA USA

In this paper, we present a way to track multiple maneuvering targets with varying time-frequency signatures. A particle filter is used to track targets that have constant speeds with changing heading directions. The target motion dynamics help the particle filter achieve an angular resolution otherwise not possible by the conventional beamforming techniques. Moreover, the particle filter has a built-in target association that eliminates the need for heuristic techniques commonly used in the multiple target tracking problems. Reference priors are used to derive the probability distribution function of the acoustic array outputs given the state of the multiple target states (MTS's). Local linearization is used to approximate the importance function used in the particle filter by a Gaussian pdf. Finally, computer simulations are used to demonstrate the performance of the algorithm with synthetic data.

Linearized Bregman iterations are low complexity and high precision approaches for solving the combined l 1 /l 2 minimization problem. In this work we give a derivation of the linearized Bregman iteration and show the links to Kaczmarz's algorithm as well as to sparse least mean squares (LMS) filters. We present a novel extension allowing to perform combined l 1 /l 2 minimization either in an LMS based adaptive filter or in a Kaczmarz based batch solution. By means of simulations we demonstrate that the performance of our extension is comparable to the original linearized Bregman approaches. Furthermore, we show that with this extension l 1 /l 2 minimization can be performed with less complexity than the corresponding l 2 minimization.

A collaborative approach to in-place sensor calibration

2nd International workshop on Information processing in sensor Networks

ISBN: (纸本)3540021116

Numerous factors contribute to errors in sensor measurements. In order to be useful, any sensor device must be calibrated to adjust its accuracy against the expected measurement scale. In large-scale sensor networks, calibration will be an exceptionally difficult task since sensor nodes are often not easily accessible and manual device-by-device calibration is intractable. In this paper, we present a two-phase post-deployment calibration technique for large-scale, dense sensor deployments. In its first phase, the algorithm derives relative calibration relationships between pairs of co-located sensors, while in the second phase, it maximizes the consistency of the pair-wise calibration functions among groups of sensor nodes. The key idea in the first phase is to use temporal correlation of signals received at neighboring sensors when the signals are highly correlated (i.e. sensors are observing the same phenomenon) to derive the function relating their bias in amplitude. We formulate the second phase as an optimization problem and present an algorithm suitable for localized implementation. We evaluate the performance of the first phase of the algorithm using empirical and simulated data.
