3D super-resolution algorithm for analysis of multi-path propagation structure

Analyzing multipath propagation structures of the mobile communication environment is an important process to develop anti-fading techniques for high speed digital radio communication. The multipath propagation structure can be clarified by estimating the DOA (direction of arrival), TOA (time of arrival) and relative power of incident waves. We have previously proposed a high resolution algorithm for analysis of the multipath propagation structure, and applied it to our multipath propagation parameter measurement equipment. It is featured by paired DOA/TOA/relative power estimation using the super-resolution techniques under the mobile communication environment. It has a capability of 3D estimation, that is 2D DOA and TOA estimation. In this paper we present the 3D super-resolution algorithm and computer simulation.
