| Abstract: | This paper gives a modified ESPRIT algorithm that is based on the correlation matrix constructed by reusing the conjugate data being rearranged. Through theoretical analysis and simulation test, it has been indicated that by comparison with the typical ESPRIT algorithm, this modified ESPRIT algorithm can improve the performances of the signal DOA estimation obviously when the snapshot number is limited. Meanwhile, its computational complexity is about equal to that of the typical ESPRIT algorithm. |
