Broadband Spectrum Survey Measurements for Cognitive Radio Applications

Popis výsledku v původním jazyce

Building penetration loss models presented in our previous paper [1] were valid for various scenarios, propagation conditions, frequency bands, and hemispherical receiving antenna pointing towards zenith. These models had a significantly rising trend ofpenetration loss with increasing elevation angle of the link in common. In this paper we show that when working with such non-isotropic terminal antennas, this trend relates primarily to the elevation trend of the reference level [2] dependent on the receiving antenna radiation pattern. This is demonstrated by the results of single-input multiple-output (SIMO) measurement trials performed at L-band in an office building and a brick building in the city of Prague. Further, based on the detailed analysis,a method to modify the elevation trend of a particular penetration loss model for different receiving antenna radiation patterns is derived and experimentally validated.
