    Abstract
  • The estimation of the source number is very important for the high resolution array signal processing. A method of the source number estimation is proposed based on the fourth order cumulant information.By constructing the fourth order cumulant matrix of array output, the number of sources is estimated according to the eigenvalue of the fourth order cumulant matrix and the minimum description length(MDL) criterion. Owing to the blind Gaussian characteristic of the high order cumulant of the signal, the presented method can effectively suppress colored noise interference to realize the estimation of the source number in colored noise background. Simulation result verifies the validity of the new method.
