Cellular system capacity with smart antennas in dispersive channels

Esteban Flores, Doeg Rodriguez, Juan Jacobo Ayala Gaytán, John E. Miller

Abstract

Smart antennas are a promising technology to increase the capacity of cellular systems. However, under severe channel conditions, the capacity gain may be small. This work presents a general methodology for the analysis of the effect of the power angular dispersion on the capacity gain when using smart antennas; linear and circular antenna arrays are analyzed. The omnidirectional case becomes particular case of the presented methodology. Finally, the maximum number of users is determined for a smart antenna system and for general antenna beam pattern and general spread characteristic.
