Recently, the authors proposed a miniaturized microphone array not utilizing the phase difference but utilizing the directivity of each microphone, namely aggregated microphones. We have already showed that the phased microphone array and the aggregated microphones can be described within the same framework. We have also showed that it is possible to apply the aggregated microphones to the various methods of the phased microphone array. However, the difference of the performance between the phased array and the aggregated microphones has not been evaluated yet. The effect of the directivity and the posture of each microphone on the performance of the aggregated microphones has not also been evaluated yet. In this paper, we evaluate the performance of DCMP (Directionally Constrained Minimization of Power) adaptive array utilizing aggregated microphones.

We consider the distributed detection of a zero-mean Gaussian signal in an analog wireless sensor network with a fusion center (FC) configured with a large number of antennas. The transmission gains of the sensor nodes are optimized by minimizing the ratio of the log probability of detection (PD) and log probability of false alarm (PFA). We show that the problem is convex with respect to the squared norm of the transmission gains, and that a closed-form solution can be found using the Karush-Kuhn-Tucker conditions. Our results indicate that a constant PD can be maintained with decreasing sensor transmit gain provided that the number of antennas increases at the same rate. This is contrasted with the case of a single-antenna FC, where PD is monotonically decreasing with transmit gain. On the other hand, we show that when the transmit power is high, the single-and multi-antenna FC both asymptotically achieve the same PD upper bound.

New analytic results on the convergence of a blind decision directed adaptive algorithm in a beamforming application are presented. The data received at multiple antennas is assumed to consist of a desired PSK signal plus additive Gaussian noise and interference. The mean improvement in output SINR obtained with one iteration of the adaptive algorithm is predicted. This is used to estimate the number of iterations required for convergence. Results are presented for BPSK and QPSK signals. The performance of the decision directed algorithm and a constant modulus algorithm is also compared.

array processing techniques for source detection and localization in an underwater acoustic environment are highly sensitive to both environmental modeling errors, such as sound propagation conditions, and sensor gain mismatch. Sonar arrays, which are normally rigorously calibrated before placement, may develop gain mismatch due to mechanical failures or local environmental variations, such as sediment build-up. In order to avoid performance degradation of detection and localization algorithms, a sensor gain calibration process can be carried out periodically. This paper proposes a maximum likelihood algorithm for sensor gain calibration in a shallow water environment. In the presence of environmental uncertainties, a robust algorithm is required, and such an algorithm is consequentially developed. The proposed method is based on the simultaneous estimation of the relative gains and the acoustic transfer function. To improve the accuracy of the sensor gain estimation, a-priori knowledge of the relationship between the sensor gains at different frequencies is exploited. Performance of the proposed calibration method is evaluated via simulations.

This paper develops a closed-form solution that improves the projection matrix method for time of arrival (TOA) source localization in the presence of sensor position inaccuracy. The projection approach is attractive because it does not require the use of an extra variable as in the traditional closed-form solution. Compared with the previous projection method, the proposed algorithm offers a closed-form solution and at the same time attains the Cramer-Rao lower bound (CRLB) performance for Gaussian noise over the small noise region. The performance of the proposed method is validated by simulations.

Personal audio systems are designed to deliver spatially separated regions of audio to individual listeners. This paper presents a method for improving the privacy of such systems. The level of a synthetic masking signal is optimised to provide specified levels of intelligibility in the bright and dark sound zones and reduce the potential for annoyance of listeners in the dark zone by responding to changes in ambient noise. Results from a simulated personal audio system indicate that less acoustic contrast is required to produce the same level of privacy when artificial masking is included in the system design, compared with relying on the masking effect of background noise alone. As privacy requirements become more challenging, the advantage gained by incorporating artificial masking increases.

Compared with uniform linear array (ULA), the coprime array can obtain larger array aperture with the same number of physical sensors, which leads to higher spatial resolution and less effect of mutual coupling. Also, the degrees of freedom (DOFs) can be increased by reconstructing the sampling covariance matrix (SCM) in virtual array domain. In this paper, we propose a robust adaptive beamforming (RAB) algorithm based on coprime array. A novel subspace based method is performed in virtual array domain to estimate the power and direction of arrival (DOA) of interference, which also obtains the ability for DOFs enhancement. Simulation results demonstrate the robustness and effectiveness of the proposed method.

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.

We propose a low complexity array processing method for differential detection of OFDM signals over underwater acoustic channels. Partial FFT technique, developed previously for mitigating inter-carrier interference in single-channel receivers operating over time-varying channels, is extended to multichannel configuration. Performance results based on simulation and experimental data demonstrate the advantage of the proposed method compared to conventional differential and coherent detection.
