In wireless communication, signal fading is the attenuation that a carrier-modulated signal experiences over a certain propagation media. The fading can be as a result of the signal undergoing multipath propagation which results in multipath fading or as a result of shadowing from obstacles affecting the wave propagation and is referred to as shadow fading and so on. One of the 3G networks, CDMA 20001x is prone to multipath fading. Thus, this paper present space diversity technique as one of the techniques involve in reducing the effect of multipath fading in CDMA20001X.The results obtained in the presence of several antenna elements and in one antenna element are simulated in Matlab. The result show that using space diversity technique reduces the BER and improves the SNR in order to enhance the channel capacity of the network.
