- Abstract
Abstract??In Wideband direct sequence code division multiple access (WCDMA) same frequency spectrum is shared through all cells simultaneously, as opposed to TDMA which is used for most 2nd generation systems. In a WCDMA system all transmitted signals turn out to be disturbing factors to all other users in the system in the form of interference limiting the system capacity. To suppress the amount of interference, fast and reliable interference controlling algorithms must be employed in next generation systems. In this paper it is shown that antenna arrays with steer able low side lobes can reduce interference in WCDMA can increase the system capacity and output signal to noise ratio of the array processing architecture. The performance metric O/P SNR of an array processing architectures is simulated in an interfering environment to demonstrate the advantage of low side lobe beamforming over adaptive antennas.
