Abstract: Based on the Least Mean Squares (LMS) principle, an online calibration algorithm with an auxiliary signal source is presented, and its improved algorithm is also given. These algorithms can be applied to the non-uniform array, and to the number of user greater than the number of antenna as well. Computer simulation demonstrates that they are effective. -
