Abstract
A new adaptive interference technique is disclosed which not only increases the cancellation bandwidth but also reduces the convergence time for the adaptive process. This new technique departs from the prior art in adaptive interference cancellation in that an estimate of the interference arrival direction coupled with a predetermined antenna response is used to establish the weight settings in the adaptive cancellation circuitry. This circuitry incorporates variable true time delay components to achieve interference cancellation over a broad bandwidth with a rapid convergence time.
