The basic strategies comprise the fix angle sweep delay and fix delay sweep angle approaches to search the uncertainty region. A simple algorithm combining the fix angle sweep delay scheme with an ordered search according to the interference level associated with each angular cell is proposed. Comparisons in different scenarios show that the proposed approach greatly improves the acquisition performance

In single-path channels where the interference is modeled as temporarily and spatially white, there exists an optimum number of angular cells minimizing the mean acquisition time. Mean acquisition times up to three times shorter
