Caracterización y modelado de canales BFWA en entornos OUTDOOR – INDOOR

Abstract

This paper presents the experimental characterization of the radio channel for outdoor-indoor communications, within the frame of Fixed Wireless Access systems. The obtained results show that the presence of line of sight minimizes the influence of the scatters that surrounds the receiver, contributing to delay spread values lower than in the non line of sigth situations. In order to reproduce the behavior of these kind of channels several models based on tapped delay lines have been developed. These models provide a good fit of the temporal channel parameters and can be useful to complete the channel collections of current and future standards.
