Joint DOA Estimation and Phase Calibration for Synchronous CDMA with Decorrelator

解相关同步CDMA系统一种联合DOA估计与相位标定算法(英文)

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.
