Abstract

The authors have studied the measured double directional channel properties based on the parametric model. The channel is modeled as the sum of the ray paths. Each of the paths is characterized by the direction of departure (DOD), the direction of arrival (DOA), and the delay time of arrival (DTOA). The complex amplitude of the path is modeled as a function of the frequency, and is represented by the values for subbands. These parameters are estimated by the SAGE-based algorithm. In this paper, the authors have investigated a furnished office environment. Dominant paths are particularly focused.
