Design of deterministic beamformers for arbitrarily configured arrays

ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Design of deterministic (fixed) beamformers for arbitrarily configured, narrow-band and broad-band arrays is addressed in this paper. A least squares procedure is described which is based on the formulation and solution of a set of eigenvector constraint equations.

Comprehensive evaluation of a two-dimensional configurable array

[1989] The Nineteenth International Symposium on Fault-Tolerant Computing. Digest of Papers, 2003
An evaluation is presented of a highly configurable architecture for two-dimensional arrays of powerful processors. The evaluation is based on an array of Warp cells and uses real application programs. The evaluation covers the areas of configurability, array survivability, and performance degradation.

Antenna Array Configuration for High-Thoughput Communications

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
Strategically selecting the location of antennas in sparse arrays can dramatically improve a communication system's resilience to both multipath fading and interference. By formulating the information theoretic capacity of a system employing an antenna array (both SIMO and MIMO) for a specified channel and interference model, we show how to optimally ...

Auto-configurable array for GCD computation

1997
A novel one-directional pass-through array for the computation of integer greatest common divisor is designed and implemented on Atmel FPGA. The design is based on the plus-minus GCD algorithm and works in LSB pipelined manner. In contrast with previous designs, the length of the new array is independent of the length of the operands: arbitrary long ...

Array Configurations That Tile the Plane

Experimental Astronomy, 2001
Future radiotelescopes need ever increasing sensitivity. With the limits of receiver sensitivity being reached this can only be achieved by increasing collecting area. The increase in antenna numbers and the multi-resolution capabilities of these telescopes, such as the SKA, means a significant departure from existing designs is needed. In this article,

Light-Controlled Configurable Colorimetric Sensing Array

Analytical Chemistry, 2019
Colorimetry is a popular gas-sensing platform, but it is typically limited to one-time use only. Here, we introduce a light-controlled configurable colorimetric sensing array to overcome this limitation. It features a photoactivated reaction between an analyte and a sensing material, such that sensing of an array element can be turned on and off with ...

Simulations of Array Configurations for the Square Kilometre Array (SKA)

2010
The Square Kilometre Array (SKA) is a new generation radio telescope for the next decades, working at metre to centimetre wavelengths. The SKA will be operational at the same time than other new optical, X-ray and Gamma-ray telescopes. It is of extreme importance that the SKA becomes competitive and complementary to those instruments.

DoA and Polarization Estimation for Arbitrary Array Configurations

IEEE Transactions on Signal Processing, 2012
In this paper, algorithms for joint high-resolution direction-of-arrival (DoA) and polarization estimation using real-world arrays with imperfections are proposed. Both azimuth and elevation angles are considered. Partially correlated and coherent signals may be handled as well.

On the Implementation of Virtual Array Using Configuration Plane

2007
A new method of designing and using virtual array in pipeline reconfigurable system is presented. This method is based on the partition of the configuration data. Using this method not only is helpful to design the virtual hardware, but also is necessary to investigate the application algorithms oriented this virtual hardware. Basing on the analysis of
