摘要：

The choice of CDMA spreading sequences predetermines the properties of the system. The properties of large area synchronous (LAS) CDMA system have been demonstrated an interference free window (IFW) compared to traditional CDMA systems. This IFW property, however, has a limited delay-offset range. It is not always possible that all the channel-induced multipath delay spread components will arrive within IFW delay-offset range if the conventional antenna is employed. In this paper, the high directive narrow beam of smart antenna system is employed to direct all the multipath propagation components to arrive within the IFW range. Moreover, smart antenna system with its mathematical model is described. The reduction of multipath propagation in smart antenna system is also described. Finally, system performance analysis in terms of BER and maximum delay spread in both conventional and smart antennas are presented.
