摘要
在保证估计精度的同时,为降低算法的运算量,将求根MUSIC算法的思想推广到一维空间谱估计搜索类算法. 在此基础上提出了求根类算法与一维谱搜索算法的统一框架,并分析了2类算法间的内在联系,最后通过计算机仿真比较了这两类典型算法的性能.
In order to reduce the computational work and keep the estimation precision, a new frame of root- type spatial spectrum estimation algorithms and one-dimension spectrum searching-type algorithms is introduced in this paper. The relation of some root-type direction-of-arrival(DOA) algorithms and the search-type DOA estimation algorithms is analyzed. Finally, performances of the root-type algorithms and one-dimension search-type DOA esti- mation algorithms are compared with each other by computer simulation.
