Abstract: “To improve coverage and performance in the CDMA as well as in MC-CDMA network, the simulation model and an evaluation method for the smart antenna system in the CDMA system is presented. Here the data service users as well as the voice services users are considered. The proposed method that can show the impact of smart antenna system on the Ec/Io coverage area and radius also presented as function of antenna type and beamwidth.The performance improvements are remarkable in the smart antenna systems. The performance of the system is evaluated in terms of Average Ec/Io, Area, Radius, Ec/Io Difference, Throughput with Number of users per sector. Both results are discussed based on various parameters like flat urban type morphology, Okumura Model for omni directional antennas air link, orthogonality factor and antenna beam width.”
