Abstract

Abstract: Root-MUSIC and PM which are aimed to reduce complexity of calculation have been discussed and compared with MUSIC in this article.Root-MUSIC algorithm reduces complexity of calculation by calculating polynomial roots,while PM algorithm by using matrix multiplication instead of eigen-decomposition.The simulation demonstrates,among the three algorithms,Root-MUSIC performs best in the case of a small amount of array elements;otherwise,PM will be better.

Key words: Root-MUSIC, PM, MUSIC, DOA
