1st IEEE sensor array and multichannel signal processing workshop (SAM 2000)

ISBN: (纸本)0780363396

In this paper, we develop simple principal and minor subspace tracking algorithms that exactly maintain the orthonormality of the subspace matrix estimate over time. Each of these algorithms use m identical Householder transformations to update the rows of the subspace matrix estimate at each time instant. Unlike many other approaches, ours have asymptotic complexities that scale linearly with the number of adaptive coefficients. We show that existing gradient-based and projection approximation subspace tracking (PAST) methods are first-order approximate versions of our proposed methods, and we also derive several more-accurate approximations. Simulations verify the excellent numerical behaviors of the proposed methods in subspace tracking tasks.

In recent years, the frequency diverse array (FDA) radar has attracted much attention due to its range-angle dependent beam-pattern. And multiple input multiple output (MIMO) radar has been widely investigated with the advantage of transmit waveform diversity. In this paper, a FDA-MIMO Inverse Synthetic Aperture Radar (ISAR) is proposed to achieve anti-jamming of ISAR imaging. LFM (Linear Frequency Modulated) and SFCS (Stepped-Frequency Chirp signal) signals are transmitted to jammer and targets respectively, and the received signals are matched filtering by the signal transmitted to the targets. So the jamming signal can't matched with the reference signal, the well anti-jamming effect can be obtained. The performance of the proposed method is evaluated by the simulation results.

We present a method for cancelation of the acoustic crosstalk between the ears of a listener using a linear loudspeaker array. This allows for controlling the signals that arise at listener's ear independently of each other so that binaural cues can be imposed. We employ superdirective near-field beamforming (SDB) over the vast part of the frequency range. Allowing the listener to move in front of the array requires the computation of a new SDB solution for each possible position of the listener, which is a computationally expensive procedure. We show that the beamformer weights exhibit a very smooth evolution for listening positions along a line parallel to the array. This makes it straightforward to parameterize pre-computed beamformer weights with a few parameters for each frequency. Upon realtime execution, the beamformer weights can be determined efficiently for any arbitrary position along the listener contour from the parameters with negligible error. Simulation results show that the proposed beamformer provides a higher channel separation than previously published solutions while maintaining robustness.

This work focuses on practical research in the field of Bluetooth 5.0 and the maximum number of Bluetooth sensors nodes in a wireless body area network (WBAN) for human activity recognition (HAR). As network topology M:1 multi-pairing is used. For the best of our knowledge no direct related work in this field can be found. We investigated how many Bluetooth connections can be simultaneously connected with different smartphones (iOS) with real sensor data and in which time intervals the data can still be processed and stored. Our results show that a maximum of 14 Bluetooth devices can be connected under practical conditions. A stable transmission with 48 bytes per package are found with most reliability in an minimal interval of 40 ms per node.

作者： Melvasalo, M Koivunen, V Helsinki Univ Technol Signal Proc Lab FIN-02015 Helsinki Finland

ISBN: (纸本)0780375513

This paper addresses the problem of blind channel estimation in a multicode DS-CDMA system in multipath environment using antenna array at the receiver. Long code CDMA system model is employed. Multicode transmission is used to provide a higher data rate to a mobile user and receiver antenna array improves the signal to interference and noise ratio (SINR). First we extend blind multicode channel estimation methods to CDMA receiver with multiple antennas. Subspace channel estimation is employed with two different pre-processing schemes. We also extend the principal component channel estimation method used for antenna array CDMA receiver to a multicode model. The performances of the proposed methods are compared in simulation using mean square error measure and bit error rates. Different numbers of interfering users are used in simulations and the impact of code selection is considered.

Multiple transmitters and receivers can be used to provide high link capacity in future wireless systems. Herein analysis of real indoor environment Multiple-Input-Multiple-Output measurements on the 5.8 GHz band is performed. The possible increase in capacity, utilizing multiple transmit and receive elements is examined. The gain possible when using channel knowledge at both transmitter and receiver is shown and the capacity dependence on the intra-element distance is examined for the experimental system and compared to simulations.

1st IEEE sensor array and multichannel signal processing workshop (SAM 2000)

ISBN: (纸本)0780363396

A cluster of commodity personal computers (PCs) is an attractive platform for signal processing, especially for applications like sensor arrays where there is significant parallelism in the computation. This paper reports the results of experiments with several small cluster configurations to explore the opportunities and limitations of this approach. Experiments included uniprocessor and multiprocessor PCs, 100 MBit/sec and 1 Gbit/sec ethernet. All experiments were receive-only, starting from raw spectrum samples provided by a wideband A/D card, and all signal processing code ran as application processes on top of standard Linux. The applications used to drive the experiments were delay and sum beamforming and the simultaneous reception of multiple AMPS cellular channels. The currently standard PCI I/O bus (32 bits at 33 MHz) was the most significant bottleneck in the experiments. This suggests that the arrival of the next generation of commodity PCs, with faster I/O busses (such as 64-bit PCI at 66 MHz), may open the door to their use as a low-cost platform for a variety of low-end realtime signal processing applications.

This paper is devoted to the problem of source detection with large sensor networks, in a context where the number of available samples N and the number of antennas M are of the same order of magnitude. We focus here on the popular likelihood penalization (LP) methods, such as Minimum Description Length (MDL) or Akaike Information Criterion (AIC). Such methods have been widely studied in the context where N >> M, and in particular the consistency of the MDL and the inconsistency of the AIC estimator were established in the asymptotic regime where N -> infinity while M remains constant. We propose here an analysis in the asymptotic regime where M, N both converge to infinity at the same rate, and using results from random matrix theory, we establish conditions on the penalty term to ensure consistency of LP methods in this latter regime. As a consequence, we deduce that the MDL method is always inconsistent while the AIC method can be consistent in certain situations.

Distributed space-time codes in wireless relay networks

3rd IEEE sensor array and multichannel signal processing workshop

作者： Jing, YD Hassibi, B CALTECH Dept Elect Engn Pasadena CA 91125 USA

ISBN: (纸本)0780385454

We apply the idea of space-time coding devised for multi le antenna systems to the communication over a wireless relay network. We use a two stage protocol, where in one stage the transmitter sends information and in the other, the relay nodes encode their received signals into a "distributed" linear dispersion code, and then transmit the coded signals to the receiver. We show that for high SNR the pairwise error probability (PEP) behaves as (log P/P)(min{T,R}), with T the coherence interval, R the number of relay nodes and P the total transmit power. Thus, apart from the log P factor and assuming T >= R, the system has the same diversity as a multi-antenna system with R transmit antennas, which is the same as assuming that the R relay nodes can fully It cooperate and have full knowledge of the transmitted signal. We further show that for a fixed total transmit power across the entire network, the optimal power allocation is for the transmitter to expend half the power and for the relays to collectively expend the other half. We also show that at low and high SNR, the coding gain is the same as that of a multi-antenna system with R antennas. At intermediate SNR, it can be quite different, which has implications for the design of distributed space-time codes.

In this paper, we present a new application of the likelihood ratio test to solve the problem of enumeration and localization of multiple emitters (sources) with a uniform linear antenna array in a multi-path environment. First, spatial smoothing is applied to the antenna array data to decorrelate signals corresponding to each path in the estimated correlation matrix and the number of paths is then counted using an information theoretic criterion. Then, MUSIC is applied with this correlation matrix to estimate the angle of arrival of all possible incident paths. In our signal model, we assume that the correlation between signals from two paths is one if they originate from the same source but zero if they are from different sources. The likelihood ratio test is then applied to each path pair using this correlation model and the angles of arrival estimated by MUSIC in order to find out if the path pair originates from the same emitter, and hence the number of emitters and their angles of arrival are estimated. The proposed algorithm on the likelihood ratio test is compared with the correlation coefficient algorithm based on minimum variance beam-forming with a performance analysis.
