Signal processing on antenna arrays has received much recent attention in the mobile and wireless networking research communities, with array signal processing approaches addressing the problems of human movement detection, indoor mobile device localization, and wireless network security. However, there are three important challenges inherent in the design of these systems that must be overcome...

In several application domains (detection systems, telecommunications, video processing, etc.) the applications deal with multidimensional data. These applications are usually embedded and subjected to real-time and resource constraints. The challenge is thus to provide efficient implementations on parallel and distributed architectures. Array-OL has been designed specifically to handle this ki...

one of the most common signals used for achieving high range resolution in radar is stepped-frequency signals. when a target is stationary in these radars, dft (discrete fourier transform) based processing is used to attain high range resolution profile (hrrp). however, in the case of moving target, due to spreading of the echo signal spectrum, dft based processing is not optimal and decreases ...

An array antenna system with innovative signal processing can improve the resolution of a source direction of arrival (DoA) estimation. High resolution techniques take the advantage of array antenna structures to better process the incoming waves. They also have the capability to identify the direction of multiple targets. This paper investigates performance of the DOA estimation algorithm name...

Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...

Distributed Acoustic Sensing (DAS) involves the transmission of laser pulses along a fiber-optic cable. These are backscattered at fiber inhomogeneities and again detected by same interrogator unit that emits pulses. Elastic deformation causes phase shifts in which converted to spatially averaged strain measurements, typically regular intervals. DAS systems provide potential employ array proces...

The use of sensor arrays in signal processing applications has received considerable attention, especially in radar/sonar processing. Sensor arrays are able to enhance desired signal reception while simultaneously suppressing undesired components through the use of directionality. The performance of traditional matched-eld beamformers is severely limited for many random signal models of interes...
