IMP-Based Fast Adaptive Beamforming Algorithms

IMP-Based Fast Adaptive Beamforming Algorithms

sensor array and multichannel signal processing workshop

作者： M. Tanaka H. Saitoh A. Sano Department of System Design Engineering Keio University Yokohama Japan

This paper is concerned with new fast adaptive beamforming algorithms which are based on the internal model principle, to deal with fast fading environment to track the desired signal changes and suppress the interferences. The LMS and RLS algorithms for constructing nulls are derived by incorporating an AR model into the weight dynamics, and then can track fast fading environment. The convergence analysis of mean and mean-square error of the weight vector are also investigated and stability condition is clarified. Numerical simulation results show that the proposed algorithms can improve tracking ability and BER performance in DS-CDMA systems

signal Strength Localization Bounds in Ad Hoc and sensor Networks when Transmit Powers are Random

sensor array and multichannel signal processing workshop

作者： N. Patwari A.O. Hero Department of Electrical Engineering & Computer Science University of Michigan Ann Arbor USA

sensor localization bounds have been derived assuming that received signal strength (RSS) measurements are performed with perfectly known sensor transmit powers. In this paper the Bayesian Cramer-Rao bound is derived assuming transmit powers are random with known prior distribution. Further, both directional measurements on each link, from i to j and from j to i, and their correlation, are explicitly considered. Results show that random transmit powers have a small (5-13%) impact on coordinate estimation bounds. However, using only the average of the directional measurements can significantly increase these bounds

Utility-Based MIMO Uplink Beamforming

sensor array and multichannel signal processing workshop

作者： J. Duplicy J. Louveaux L. Vandendorpe Communications and Remote Sensing Laboratory Department of Electrical Engineering Université catholique de Louvain Louvain-la-Neuve Belgium

This paper addresses the design of transmit and receive beamformers in a multiple-input multiple-output (MIMO) uplink system. To optimize the beamformers, we introduce a new utility function defined as a weighted difference between users' rates and their transmit power. This new criterion allows to take into account whether the users are more rate-sensitive or power-sensitive. Beamformers and power allocation are iteratively computed by resorting to the framework of non-cooperative game theory

The use of multi-dimensional wave extraction algorithm for a multi-receivers axial transmission ultrasound device used in bone evaluation is proposed. As far as we know, multi-dimensional signal processing techniques have never been implemented in this configuration. A SVD-based wavefront extraction is implemented for the characterization of an energetic low frequency contribution. Velocity accuracy is estimated on a synthetic dataset. Furthermore, the energetic low frequency removal is illustrated on in vivo signals. Results are promising as for the application of multi-dimensional techniques in medical ultrasound used in transmission

Cognitive Radar Networks

Cognitive Radar Networks

sensor array and multichannel signal processing workshop

作者： S. Haykin McMaster University Hamilton ONT Canada

This paper describes the use of cognitive radar networks for the reliable surveillance of an environment where the likelihood of the presence of uncooperative targets is high. Despite the limited effectiveness of amplitude as a radar discriminant, through the clever use of detection through tracking, the detection performance of the noncoherent radar is enhanced. Further improvement in overall performance can be attained through the adaptive illumination of the environment, made possible by linking the receiver to the transmitter via a feedback channel, which, in turn, makes the tracking adaptive, and sensor fusion performed in the central base station

sensor array and multichannel signal processing workshop

作者： Kehu Yang Xueyao He E. E. Research Institute Xidian University Xi'an China

It is known that blind timing synchronization of OFDM systems can be realized for AWGN channels using the redundant information of cyclic prefix. In this paper, we extend the blind method to the case of array receivers via adaptive beamforming, and a new approach is proposed to improve the synchronization accuracy for high data rate OFDM systems, where rich multipath rays are present. The extended method is to coherently combine the desired signals of array receivers and suppress the undesired signals using adaptive beamforming. And the approach is to reduce the effect of multipath rays on synchronization. Simulation results show that in rich multipath scenarios the approach works effectively both in the absence and the presence of carrier frequency offset

sensor array and multichannel signal processing workshop

作者： S. Sirianunpiboon S.D. Howard J. Asenstorfer Defence Science and Technology Organisation Edinburgh Australia

It is well known in array processing that general multiple signal model based approaches for direction of arrival estimation, such as maximum likelihood (ML) or maximum a posteriori (MAP) estimation, are optimal. The major drawbacks of these approaches, is that not only do we need to know the number of signals a priori, but these methods also involve multivariate nonlinear maximizations which can often lead to an unacceptably large computational overhead. In this paper we propose a hierarchical Bayesian analysis for high accuracy direction finding and the resolution of closely spaced signals. The approach is to use a one signal model posterior distribution to obtain an initial coarse location of the signals. We then take each peak found and analyze it locally with a two signal model. In this way the computational load is kept modest as the optimizations are carried out only locally around the peak and there is no need to know, a priori, the number of signals. It is shown that this approach also provides a basis for the development of robust beamformers through the use of Laplace asymptotic expansions.

Statistical Identifiability of Multidimensional Frequency Estimation with Finite Snapshots

Statistical Identifiability of Multidimensional Frequency Es...

sensor array and multichannel signal processing workshop

作者： Jun Liu Xiangqian Liu Department of Electrical and Computer Engineering University of Louisville Louisville KY USA

Recently much progress has been made to improve the identifiability of frequency estimation from one snapshot of multidimensional frequency data mixture. However, in the case of multiple snapshots (or multiple trials of experiments), there are few identifiability results available. With multiple data snapshots, most existing algebraic approaches estimate frequencies from the sample covariance matrix. In this work we provide an upper bound on the maximum number of multidimensional frequencies that can be estimated for a given data size with finite snapshots. We show how the identifiability bound increases as the number of snapshots increases. An eigenvector-based algorithm is also obtained for N-D frequency estimation. Simulation results show the proposed algorithm offers competitive performance when compared with existing algebraic algorithms but with reduced complexity

Maximum Likelihood Localization using GARCH Noise Models

Maximum Likelihood Localization using GARCH Noise Models

引用

sensor array and multichannel signal processing workshop

作者： H. Amiri H. Amindavar R.L. Kirlin Department of Electrical Engineering Amirkabir University of Technology슠 Tehran Iran Department of Electrical Engineering University of Victoria Victoria Canada

In this paper we propose a new source localization method using additive noise modeling based on generalized autoregressive conditional heteroscedasticity (GARCH) time-series. We use the GARCH noise model in the maximum likelihood (ML) sense for the estimation of direction of arrival (DOA) of impinging narrowband sources. In an actual application, the measurement of additive noise in a natural environment shows that noise can sometimes be significantly non-Gaussian and non-stationary. GARCH time-series are feasible for heavy-tail probability density function (PDF) and time-varying variances of stochastic noise process. We examine the suitability of the proposed method using simulated and experimental data

sensor array and multichannel signal processing workshop

作者： A.C. Gurbuz J.H. McClellan Center for Signal and Image Processing School of Electrical and Computer Engineering Georgia Institute of Technology Atlanta GA USA

An iterative technique for detecting linear features in 2D images based on the Radon transform is developed. The algorithm is suitable for processing ground penetrating radar (GPR) and seismic images to find underground pipes and tunnels. Detection is performed in the Radon transform space. The length and width of the linear object area are estimated and the corresponding portion of the image is removed at each iteration. The algorithm has the advantage of detecting very weak linear objects, which are barely detected by existing detection algorithms, in Radon transform space. The proposed algorithm is tested on both simulated and experimental data measured from a laboratory scale model area. Results show successful detection of strong and weak linear objects
