Quad-quaternion MUSIC for DOA Estimation_通信工程毕业论文 全部作者: 龚晓峰 徐友根 刘志文 第1作者单位: 北京理工大学信息科学技术学院 论文摘要: A new quad-quaternion model is herein established for a six-component electro-magnetic vector-sensor array, under which a multidimensional-algebra based direc-tion-of-arrival (DOA) estimation algorithm, termed as quad-quaternion MUSIC (QQ-MUSIC), is proposed. This method provides DOA estimation (decoupled from polarization) by exploiting the orthogonality of the newly defined ‘quad-quaternion’ signal and noise subspaces. Due to the stronger constraints that quad-quaternion or-thogonality imposes on quad-quaternion vectors, QQ-MUSIC is shown to offer great robustness to model errors, and thus is very competent in practice. Simulation results have validated the proposed method. 关键词: Array signal processing, direction of arrival estimation, polarization, quad-quaternion. (浏览全文) 发表日期: 2008年04月03日 同行评议: (暂时没有) 综合评价: (暂时没有)
