In this paper, a now narrowband beam former with derivative constraint is developed for wideband and coherent jammers suppression. The so-called IQML algorithm with linear constraint, which is used to estimate the unknown directions of the jammers in signal-free environment, is shown to be an inappropriate constraint estimator. In this paper, a new IQML algorithm with a norm constraint is considered, which is a consistent estimator and can be used to achieve desired performance. It can be also employed in the CDMA systom for MAI suppression. We show that it outperforms the approach with the linear constraint used in the narrowband beam former, in terms of directional pattern, output SINR and nulling capability for wideband and coherent jammers suppression.
