Manifold Separation Based DOA Estimation Using Fourth-order Cumulant
Yaxing Yue, Yougen Xu, Zhiwen Liu · 2020
Direction-of-arrival estimation of non-Gaussian signals is studied in this paper by incorporating fourth-order cumulant with an array of arbitrary configurations. The fourth-order cumulant based closed form polynomial coefficients have been provided. The corresponding higher-order (more than fourth-order) statistics based method can also be derived similarly. The computational complexity analysis is also given. Simulation results are included to illustrate the performance of the proposed method.
