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 DOA estimation algorithm for two-dimensional (azimuth / elevation) CDMA systems is proposed. By solving the correlation processing, the two-dimensional ESPRIT algorithm can be used to solve the corresponding two-dimensional azimuth / high-low-DOA estimation problem. Simulation results show that this algorithm can effectively and accurately solve the problem of two-dimensional DOA estimation of signals.
