We make improvement on the generalized Steiner estimator (GSE) which is used in array antennas for the TD-SCDMA system. By employing the spatial signature comprehensively, we proposed a novel noise resisting method which is based on a simple DOA method and uses directional vectors and compared this method with those in reference [1] and [2]. For the defined vehicular environment, simulation results show that this novel method in this paper can achieve almost the same performance as that in reference [2] and the above two methods both outperform that in reference [1]. In addition, comparing with the method in reference [2], the proposed novel method has less computation.
