摘要
智能天线是当前通信领域的热门技术之一。提出了一种基于智能天线的有效的超分辨二维DOA估计算法。该算法同时在空域和时域进行变换,产生大量虚拟阵元,使得阵列在空间的阵元数大量增加,实现了对二维DOA的有效估计。仿真结果验证了此结论。
The smart antenna is one of the most attractive technologies in mobile com munications.In the paper,a high -re solution algorithm is presented to estimate 2-D DOA.Through virtual transformin g in space and time domain,a large amo unt of virtual elements is produced.The algorithm realizes the 2-D DOA estimation efficiency.I t is shown by the simulation experime nts.
