Abstract :
A joint direction of arrival (DOA) estimation and phase calibration for synchronous CDMA system with decorrelator is presented. Through decorrelating processing DOAs of the desired users are estimated independently and all other resolved signal interferences are eliminated. Emphasis is directed to applications in which sensor phases are in error. It is shown that accurate phase calibration in conjunction with their use in high-resolution DOA estimation are achieved for the decoupled signals.
