摘要： This paper derives the stochastic Cramer-Rao bound (CRB) for the direction of arrival (DOA) estimation accuracy for noncircular sources in the noise modelled by Cauchy process, and expands it to the general alpha-stable noise situations. The performance of the EXC-NC-MUSIC, which is proposed by the authors, in a wide range of impulsive noise environments is examined via simulation experiments and evaluated with the CRB.
