Description: The large volumes of information necessary to support today'swarfigher require the development of new technology to provide this type of secure, high data ratecommunication. The flexibility ofcellular communications makes it an excellent choice for thispurpose. Currently availablecellular communications     systems are narrowband; that is,they cannot support high data rateapplications such as video, full Internet connection, and teleconferencing. Simplyincreasing the bandwidth of theexisting systems will result insevere degradation due to frequency-selective fading,resulting in loss of quality and reliability. Instead, a new wideband cellular system can be usedfeaturing a multicarrier, codedivision multiple access (CDMA)method. This type of system minimizes the effects of frequency-selective fading while reducing the probability of detection and     interception. The limiting factor in this type of system' is co-channel interference. This thesis focuses on analyzing the co-channelinterference on the forward channel of the proposed CDMA cellular system and investigating     methods such as sectoring andmicrozoning in an effort to reducethat interference.
