Abstract :

The advancing technologies in mobile communication systems can integrate a wide variety of communication services like high speed data, video and multimedia traffic as well as voice signals. Using WCDMA (Wideband Code Division Multiple Access), the radio access technology in 3G has many advantages like highly efficient spectrum utilization, variable user data rates. The capacity of the system is increased by implementing intra cell reuse concept. The Multipath & Co–channel interference are the two major impairments usually limiting the capacity and performance of mobile communications. Smart antennas can effectively reduce those impairments by focusing the radiation only in the desired direction and placing nulls in the interferers via adaptive updating of weights and adjusting itself to changing traffic conditions or signal environments. This paper discusses about the performance of WCDMA FDD downlink system for different data rates on diferent multipath channels.
