Development of Parallel Architectures for Sensor Array Processing Algorithms

Abstract

The high resolution direction-of-arrival (DOA) estimation has been an important area of research for number of years. Many researchers have developed number of algorithms in this area. Fast advancement in the areas of Very Large Scale Integration (VLSI), Computer Aided Design (CAD) and Application Specific Integrated Circuit (ASIC) design, has made possible the development of dedicated hardware for sensor array processing algorithms. In this research we have first focussed our research for the development of parallel architecture for Multiple Signal Classification (MUSIC) and Estimation of Signal Parameter via Rotational Invariance Technique (ESPRIT) algorithms for the narrow band sources. The second part of this research is to perform DOA estimation for the wideband sources using two algorithms. All these algorithms have been substituted with computationally efficient modules and converted them to pipelined and parallel algorithms. Parallel Architectures for the computation of these algorithms and architectures has been developed. Simulations of these algorithms and architectures has been performed and more detailed simulations are in progress.
