Alpha稳定分布噪声环境下类M估计相关的DOA估计新算法
M-estimate like correlation based algorithm for direction of arrival estimation under alpha-stable environments
摘要
Abstract
A novel class of bounded statistics, namely, the M-estimate like correlation (MELC) for independently identic-al distributed symmetric alpha-stable ( S Sα) random variables was defined. Based on the MELC matrix for the array sensor outputs, a new algorithm for direction of arrival (DOA) estimation in the presence of complex S Sα noise was proposed. The comprehensive Monte-Carlo simulation results show that the MELC-MUSIC algorithm not only outper-forms the fractional lower order statistics (FLOS) based MUSIC algorithms under low SNR conditions and multi-source signals environment, but also is robust with circular and noncircular signals.关键词
