中文说明：
为了实现DOA和时延的联合估计,提出了一个无线通信中高分辨率的联合角度和时延估计方法,该方法不需要对参数进行搜索,利用空时矩阵的特征向量和特征值分别估计DOA和时延,通过特征值和特征向量的对应关系,估计的参数可以自动实现配对, 只要各路径信号的DOA和时延不同时接近此方法都可以适用,与JADE-MUSIC,JADE-ESPRIT和SI-JADE算法相比,该算法具有较好的鲁棒性和较小的估计误差。仿真结果证明了该算法的有效性。
English Description：
In order to realize the joint estimation of DOA and time delay, a high-resolution joint angle and time delay estimation method in wireless communication is proposed. This method does not need to search the parameters, and uses the eigenvectors and eigenvalues of space-time matrix to estimate DOA and time delay respectively. Through the corresponding relationship between the eigenvalues and eigenvectors, the estimated parameters can be automatically paired, Compared with jade-music, jade-esprit and si-jade, this algorithm has better robustness and smaller estimation error. Simulation results show the effectiveness of the algorithm.
