In this paper, we study a Wireless Passive sensor Network (WPSN) that employs binary coded differential delay line surface acoustic wave (SAW) devices to monitor temperature in a harsh conditioned environment the sensors are individually addressed by different reflector patterns. the number of sensors in the system is related to the coded reflectors pattern length which itself is limited by the size constraint of sensors. We propose a new sectorized system model for the WPSN by utilizing a phased circular antenna array to increase the number of sensors in the system that yields higher sensing spatial accuracy. Moreover, the sensing accuracy is further improved by a new two-step detection procedure that purifies the response signal and removes the interference of undesired sensors1. © 2011 ieee.

Non-contact capacitive ECG measurements (cECG) have applications in various unobtrusive and ubiquitous systems. However, cECG signals are frequently corrupted by interference and motion artifacts. In this work array processing methods, such as blind source separation, were used to reduce the impact of motion artifacts on QRS detection. the capacitive sensor array was integrated in a bed mattress and covered with two insulating sheets. the array processing methods were compared in terms of their QRS detection error rates (De). Results of our study with five healthy subjects in different recording conditions showed that, when using array processing methods, QRS detection performance during body motion can be substantially improved (De reduced from 0.46 on raw sensor data to 0.06 for a channel difference method). We concluded that array processing is a promising approach to achieve motion-resistant QRS detection and thus suggest wider use of capacitive sensor arrays. © 2011 ACM.

A new sensor interface for detecting notes in the musical audio signals is proposed. Our sensor interface is able to transform acoustic pressure, caused by a sound wave of polyphonic piano music, into a musical score, that is a symbolic representation of musical notes. We focuses on note attack instant (onset) and note name (pitch). signal processing techniques based on the Constant-Q Transform (CQT) are used to create a time-frequency representation of the signal. In particular, we propose a supervised classification methods based on sparse Non-Negative Matrix Factorization (NMF) to detect note pitch. We present a collection of experiments using the Inventions and Sinfonias BWV 772-801 of the composer J. S. Bach. © 2011 ieee.

ieee International workshop on Computational Advances in Multi-sensor Adaptive processing (CAMSAP)

作者： Daniel R. Fuhrmann Department of Electrical and Computer Engineering Michigan Technological University Houghton MI USA

We explore transmit signaling and receive signal processing strategies for a notional MIMO radar system consisting of widely distributed phased arrays. the assumptions are that within a phased array, there is a fixed rigid geometry and perfect phase synchronization, and there is a single look at the target. In constrast, between phased arrays there is imperfect phase synchronization and multiple views of the target. the relative advantages and disadvantages of coherent and orthogonal signaling in such a model are explored through simulation.

ieee International workshop on Computational Advances in Multi-sensor Adaptive processing (CAMSAP)

作者： David Ayllón Roberto Gil-Pita Manuel Rosa-Zurera Applied Signal Group University of Alcala Madrid Spain

Modern hearing aids include signal processing algorithms to improve the speech intelligibility by means of a microphone array, which can be monaural or binaural. In both cases, the signals are distorted by the well-known head-shadow effect that must be considered in the design. the main goal of this paper is to find the best microphone array configuration for in-the-canal hearing aids, constrained by the reduced dimension of such devices, in order to maximize the output gain and intelligibility when the array is steered to the desired direction. For this purpose, a total of 12 different array arrangements are compared, in terms of the array gain and intelligibility obtained by a Minimum Variance Distortionless Response (MVDR) beamformer, which also considers the head-shadow effect. the highest gain and intelligibility are obtained by a binaural array composed by a total of 8 microphones, 4 in diamond-shaped alignment in each ear. the results show the level of improvement achieved by increasing the number of microphones as well as using binaural arrays, giving rise to a compromise between the complexity of the array and the desired enhancement.

Tomography, used to create images of the internal properties and features of an object, from phased array ultasonics is improved through many sophisiticated methonds of post processing of data. One approach used to improve tomographic results is to prescribe the collection of more data, from different points of few so that data fusion might have a richer data set to work from. this approach can lead to rapid increase in the data needed to be stored and processed. It also does not necessarily lead to have the needed data. this article describes a novel approach to utilizing the data aquired as a basis for adapting the sensors focusing parameters to locate more precisely the features in the material: specifically, two evolutionary methods of autofocusing on a returned signal are coupled with the derivations of the forumulas for spatially locating the feature are given. Test results of the two novel methods of evolutionary based focusing (EBF) illustrate the improved signal strength and correction of the position of feature using the optimized focal timing parameters, called Focused Delay Identification (FoDI).

作者： Emil Björnson Mats Bengtsson Gan Zheng Björn Ottersten Signal Processing Lab KTH Royal Institute of Technology Sweden Reliability and Trust (SnT) University of Luxembourg Signal Processing Lab KTH Royal Institute of Technology

Coordinated beamforming can significantly improve the performance of cellular systems through joint interference management. Unfortunately, such beamforming optimization problems are typically NP-hard in multicell scenarios, making heuristic beamforming the only feasible choice in practice. this paper proposes a new branch-reduce-and-bound algorithm that solves such optimization problems globally, with a complexity suitable for benchmarking and analysis. Compared to prior work, the framework handles robustness to uncertain intercell interference and numerical analysis shows higher efficiency.

ieee International workshop on Computational Advances in Multi-sensor Adaptive processing (CAMSAP)

作者： Johannes Lindblom Eleftherios Karipidis Erik G. Larsson Communication Systems Division Department of Electrical Engineering (ISY) Linköping University Linkoping Sweden

We study the two-user multiple-input single-output (MISO) interference channel for the scenario where the transmitters have perfect channel state information and employ single-stream beamforming. We assume that the receivers are able of decoding the data from both transmitters. Hence, the signal from the interfering transmitter might be decoded, treating the desired signal as noise, and subtracted from the received signal. We propose an efficient method for finding the Pareto boundary of the corresponding achievable rate region. this method has a complexity which is constant in the number of transmit antennas.

ieee International workshop on Computational Advances in Multi-sensor Adaptive processing (CAMSAP)

作者： Michael Leigsnering Abdelhak M. Zoubir Mounir Ghogho Signal Processing Group Technische Universität Darmstadt Darmstadt Germany School of Electronic and Electrical Engineering University of Leeds Leeds UK

High resolution wideband near-field imaging requires wideband signals and large array apertures. Hence, a large amount of data needs to be processed in the image formation step. the computational load of the standard delay and sum beamformer stems from the calculation of the focus delays and the evaluation of the sums over the measurements. We propose an approach tackling the problem of calculating the focus delays. Provided a uniform rectangular array (URA) is used, the image can be evaluated on a well tailored discrete grid such that most focus delays are redundant. Now by calculating only the non-redundant values we can reduce the numerical complexity significantly. the above approach is combined with fast beamforming based on the non-equispaced fast Fourier transform (NFFT). We demonstrate the good performance with experimental results from a through-the-wall radar imaging system.

ieee International workshop on Computational Advances in Multi-sensor Adaptive processing (CAMSAP)

作者： Adrian Schad Marius Pesavento Communication Systems Group Technische Universität Darmstadt Darmstadt Germany

In this paper, we extend the concept of the one-directional multiuser peer-to-peer amplify-and-forward relaying scheme to that of a bi-directional two-phase relaying scheme. the relay weights are chosen to maximize the minimal received quality-of-service of all the users under constraints on the individual and the total power at the relays. the computation of the relay weights is accomplished by approximately solving a non-convex optimization problem using a sequential convex programming algorithm of low complexity. In our simulations, the proposed bi-directional relaying scheme outper-formed the one-directional multiuser peer-to-peer scheme.
