On antenna- and frequency diversity in GSM related systems (GSM-900, DCS-1800, and PCS1900)
Preben Mogensen, Jeroen Wigard · 2002
This paper analyze the performance of two branch antenna diversity in GSM related systems. Several combining techniques for both up- and downlink are analyzed. Frequency diversity obtained from slow frequency hopping in GSM is also considered. Finally antenna diversity results for a non-ideal antenna configuration, i.e., introducing antenna branch cross-correlation or cross polarization discrimination (XPD) are presented.
