| Abstract(in English) | Superresokution techniques have been widely noticed as high-resokution direction-of-arrival methods for wave propagation analysis in mobile communication. Generally, the technique that can revolve multipath waves is applied only to uniform array, and its resolution depends on the array length. Weiss et al. reported a interpolated array techniques which leads to the virtual aaray having long array length. In this report, we evaluate convergence property of the method by computer simulations, and propose a improved technique. Also, estimation errors of the method are evaluated. |
