Abstract:

This work performed a review of wide-band DOA algorithms in the literature which was accumulated for more than 30 years. We have reviewed the most relevant ones with the goal of implementing them in hardware for real time applications. We have discovered a class of computational requirements that would be required in all these algorithms. We have also given reviews and challenges. We were able to cut through all the mathematics and convert algorithms into simple arithmetic operations. This step is very useful in visualizing an architecture. We have filled a gap between the design of computer hardware especially special purpose parallel architectures and available algorithms for various wide-band DOA algorithms. This work was the first step in sorting out which algorithm is appropriate for further study and for its hardware implementation for real time applications.
