PROJECT TITLE :

Efficient Wideband DOA Estimation Through Function Evaluation Techniques - 2018

ABSTRACT:

This Project presents an economical analysis methodology for the functions involved within the computation of direction-of-arrival (DOA) estimators. The strategy may be a combination of the Chebyshev and barycentric interpolators, and makes use of the discrete cosine remodel. We have a tendency to present two applications of this technique. The first is for reducing the complexity of the road searches in three wideband DOA estimators: incoherent multiple signal classification, take a look at of orthogonality of projected subspaces, and deterministic most probability (DML). And therefore the second application is a procedure to compress the wideband DML cost operate, therefore that it is shaped by simply a few summands. This compression entails a discount in complexity by a massive factor. The evaluation method and its applications are numerically assessed in several numerical examples.
