This paper is aimed at enhancing the performance of CDMA20001x using antenna diversity technique in order to accommodate much subscribers on the network. Real time measurement involving measurement of received signal strength and signal to interference and noise ratio were carried out on a CDMA20001x network in Asaba, Delta state of Nigeria. This paper also presents simulations that was done on Matlab version 7.5 to determine the BER performance of the CDMA20001X with and without antenna diversity. Results obtained from the real time measurements showed that CDMA20001x as one of the 3G network is prone to the effect of multipath fading and multiple access interference and these effect need to be minimized using antenna diversity. The results of the BER performance of CDMA20001x with antenna diversity showed a significant improvement on the performance of the network compared to the result without antenna diversity.
