摘　　要：提出了一种新颖的解相关同步CDMA系统二维(方位/高低)波达方向(DOA)估计算法。 通过解相关处理, 可通过两次运用一维ESPRIT算法解决相应的二维方位/高低波达方向的估计问题。 仿真结果表明本算法能有效、精确地解决信号的二维DOA估计问题。A novel ESPRIT based two-dimensional direction of arrival (DOA) estimation (azimuth and elevation angle estimation) algorithm for S-CDMA system with decorrelator is presented. Through decorrelating processing we can employ one-dimensional ESPRIT algorithm twice to solve the corresponding two-dimensional azimuth and elevation angle estimation problem. Simulation results show that the proposed algorithm estimates two-dimensional DOAs of signals effectively and accurately.
