Traffic Modelling of Cellular Mobile Communications Systems Operating with Code Division Multiple Access

This thesis concerns the traffic modelling of cellular mobile communications networks operating with code division multiple access (CDMA). Such systems have come into prominence in recent years in conjunction with the development and validation of the Qualcomm CDMA cellular system. Most research has concentrated on transmission issues and existing capacity analyses inevitably assume fixed and spatially uniform user distributions. However such capacity specification provides little information on how the network will behave under a stochastically varying load. This traffic behaviour is critical in order to properly design and manage a network but to date, there have been few contributions in this area. The goal of this thesis is to develop analytic techniques for traffic modelling that can be used in the performance analysis and design of CDMA cellular networks. As a first step, each cell is modelled as an independent M=G=1 queue and traffic capacity assessed based on the maximum Erlang..
