dc.description.abstractPresently, the uniform linear array (ULA) is the most commonly used antenna system for a sectorized cell system like the commercial cellular systems. However, in many omni-directional cell communication systems, such as the ground-based military communications, interest in using the uniform circular array (UCA) has greatly increased. This thesis examines the use of an equally-spaced circular adaptive antenna array at the mobile station for a typical coded direct sequence code division multiple access (DS-CDMA) communication system. This thesis analyzed the performance of a randomly orientated adaptive UCA in the forward channel (base station to mobile station) of a coded multi-cell DS-CDMA system. Using a 3- and 4-element UCA, the ca-pacity and performance of different cellular systems under a range of shadowing conditions, with and without an-tenna sectoring at the base station, and various user capacities were simulated using the Monte Carlo simulation. The results for both ULA, as studied in [7], and UCA were compared and presented in this thesis.en_US
