Abstract
An improved direction of arrival (DOA) estimation algorithm with sensor gains and phase uncertainties for synchronous CDMA system with decorrelator is 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 gain and phrase are perturbed that are often happened actually. It is shown that improved DOA estimation can be achieved for decoupled signals by gain and phase pre-estimation procedures.
