Abstract :
In this paper, a fast subspace extended cyclic MUSIC algorithm is presented for DOA estimation of cyclostationary signals. The proposed method replaces the singular value decomposition required in the extended cyclic MUSIC algorithm with the matrix inverse-free version of the fast rational approximation algorithm. It has comparable resolution power, less accuracy, and lower computational complexity than the extended cyclic MUSIC algorithm.
