Abstract :
This paper considers the performance of a DS-CDMA system which employs adaptive antenna technology at the basestation site of a microcell. Results for a typical microcellular environment produced with the help of a ray tracing tool highlight the behaviour of the adaptive antenna and with the help of a Monte-Carlo type DS-CDMA capacity analysis, the potential performance enhancement of the system is evaluated. Finally, scenarios with inter-cell interference and moving users are discussed, and the fixed beam steering and the reduced sidelobe techniques are considered against the adaptive antenna technique
