Angle-of-arrival estimation based on weighted cyclic spectrum
Zhitao Huang, Zhou Yiyu, Jiang Wenli · 2002
For cyclostationary signals, a generalized sensor array data model is presented and a new angle-of-arrival (AOA) estimation method based on weighted cyclic spectrum - GSC-SSF is developed in this paper. The proposed algorithm is more convenient and effective in forming the data matrix or the covariance. matrix for the MUSIC or ESPRIT algorithm to estimate AOA and suppress noise. Simulation results show better performance for the new method.
