- 論文の詳細を見る
This paper studios on a fast approach for the eigonproblems of correlation matrices used in direction-of-arrival (DOA) estimation algorithms, especially for the ease that the number of arriving waves is a few. The eigenvalues and the corresponding eigenvectors can be obtained in a very short time by the algebraic solvent of up to quartie polynomials. We also confirm that the present approach does not make the accuracy worse when it is implemented by finite word-length processors like digital signal processor (DSP) or field programmable gate array (FPGA).
