摘要
提出一种低复杂度的旋转不变技术信号参数估计方法,只需要利用某一个信号的导频信息就可以实现对所有信号和干扰的波达方向进行快速估计,不需要估计协方差矩阵和对其作特征值分解,具有低复杂度和小运算量的特点.
A low computational complexity ESPRIT method is developed to fast estimate the direction-arrival（DOA） for statistically independent signals. The novel method exploits the training sequences of a desired signal to extract all the directional parameters of the signals and interferences. The proposed method does not need to form the sample covariance matrix or compute its eigenvectors, thus indicating much lower computational complexity. Finally, the effectiveness of the presented approach is verified by numerical results.
