Abstract:
A joint direction of arrival(DOA)estimation and phase calibration for synchronous CDMA system with decorrelator are presented. Through decorrelating processing DOAs of the desired users can be estimated independently and all other resolved signal interferences are eliminated. Emphasis is directed to applications in which sensor phases may be in error. It is shown that accurate phase calibration in conjunction with their use in high-resolution DOA estimation can be achieved for the decoupled signals.
提出了解相关同步CDMA系统一种联合波达方向(DOA)估计与相位标定算法.通过解相关处理可消除分离出的所有干扰信号, 使目标用户的DOA可独立地进行估计.文中着重研究了阵列传感器相位存在误差时的估计情况.仿真结果表明可实现精确的相位标定及解藕信号的高分辨DOA估计.
