多重信号分类(Q 音乐) 算法通常要求的四元数四维光谱估计到达(DOA ) 和极化参数的方向的山峰搜索,它将导致巨大的计算负担。一个尺寸减小 Q 音乐算法(DRQ 音乐) 基于塑造 L 的数组被介绍在这篇论文减少计算复杂性。建议算法把驾驶向量划分成三部分,并且独立估计每部分,因此, DOA 和极化参数能仅仅由 N 时间被估计一个维光谱山峰搜索,在 N 表示来源的地方,数。而且,对火柴没被要求。最后,模拟例子表明建议算法的有效性和可行性。
The quaternion multiple signal classification(Q-MUSIC)algorithm generally requires four-dimensional spectral peak search to estimate the direction of arrival(DOA)and polarization parameters,which would result in the huge computation burden.A dimension reduction Q-MUSIC algorithm(DRQ-MUSIC)based on L-shaped array is presented to reduce the computational complexity in this paper.The proposed algorithm divides the steering vector into three parts,and estimates each part separately,thus DOA and polarization parameters can be estimated only by N times one-dimensional spectral peak search,where N denotes the sources number.Besides,pair match is not required.Finally,simulation examples demonstrate the effectiveness and feasibility of the proposed algorithm.
