Experimental evaluation of polarization diversity gains for 1.8 GHz GSM downlink signals

This paper presents an experimental evaluation of polarization diversity gains obtained for GSM downlink signals in the 1.8 GHz band. Data were acquired with a portable two-branch receiver, developed to include a signals selection diversity method, which was displaced at walking speed inside buildings featuring a variety of room sizes. The experimental setup and relevant environmental conditions pertaining to data collection are herein described. Diversity gains cumulative distribution functions resulting from raw data processing are analyzed.
