Performance of two branch space and polarization diversity at 900 MHz

This work summarizes the results of a measurement campaign undertaken to evaluate the performance of two branch space and polarization diversity schemes at 900 MHz in different environments (urban, suburban, rural flat and rural hilly). A total number of 783 runs were made covering these sites and using different transmitter antennas (vertical polarized roof-top antenna, handheld randomly inclined) at differents speeds (walking, by car at 30 up to 80 km/h). Comparison between the two types of diversity schemes have been made through calculation of the statistics of mean received signal level, diversity gain, incremental diversity gain and envelope cross-correlation.
