On the bit error rate for the uplink of CDMA cellular systems with smart antennas

The influence of the directivity of the beampattern of smart antennas on the bit error rate for the uplink of CDMA (code division multiple access) based mobile communications systems is investigated. We use Liberti's and Rappaport's (1994) model for the bit error rate. The asymptotic behavior of the bit error rate as a function of the directivity of the beam pattern is also given.
