Book Description
One of today's problems in signal processing is the identification of direction-of-arrival (DOA) for multiple broad-band sources. Many algorithms have been proposed in the literature, however, the algorithms are highly complex and require a lot of computing power. New technologies in the past two decades have decreased the cost of digital hardware, and its speed has increased to such an extent that digital signal processing has replaced a great deal of analog signal processing. This thesis presents a digital-domain parallel-pipelined architecture capable of computing the DOA of multiple broad-band sources in real-time. Broad-Band Signal-Subspace Spatial-Spectrum (BASS-ALE) Estimation algorithm has been selected for DOA estimation and has been simulated and verified through computer software programs. The BASS-ALE algorithm has been modified and parallelized. The parallel algorithm has been mapped on an architecture which is suitable for real-time computation.

Book Description
High resolution direction-of-arrival (DOA) estimation is important in many sensor systems. It is based on the processing of the received signal and extracting the desired parameters of the DOA of plane waves. The estimation of angle of arrivals of multiple broadband sources has been carried out in a variety of ways over the past few years. In this research an algorithm for broadband DOA estimation using a simple bilinear transformation matrix is investigated and a parallel and pipelined architecture is developed. When compared to other coherent approaches, this algorithm has the advantages of being non-iterative and does not require any initial estimates of the angles of arrival and all angles are computed from a single step of coherent subspace calculations. Hence it is a very suitable algorithm for computation of DOA using dedicated hardware. The advances in the area of Very Large Scale Integration (VLSI) have made it possible to design special purpose hardware which has the advantage of very high speed and overall lower system cost when compared to a system which runs off a general purpose computer.
