It has been known that the performance of conventional GSC is quite sensitive even to pointing error. In conjunction with the joint desired user's code-aid and signal subspace estimating approach, the proper quiescent weight vector and blocking matrix of GSC can be obtained to suppress the leakage of desired signal. However, space signature is estimated by exploiting the knowledge of the spreading code of the user of interest and the orthogonality between noise and signal subspaces. In this paper, the space-time signature estimation can be integrated jointly. Therefore, the desired signal cancellation does not occur; even the pointing error is relatively large. Computer simulation results show the effectiveness of the proposed approach.
