... adaptive algorithms, including direct data domain least square, can be significantly degraded in the presence of mutual coupling among array elements. In this paper, a new adaptive algorithm was proposed ... The second drawback is that the estimation of the covariance matrix requires the storage and processing of the secondary data. This is computationally intensive, requirin...

With increasing a, the interval in which the utility function makes a transition from small ... evaluation of the function u at each inner iteration. As a result, the overall gain in terms of complexity clearly depends on the cost associated with evaluating u. 5...
