Diversity signal processing requirements of direct sequence CDMA networks in cellular and micro-cellular environments

The diversity signal processing requirements versus bandwidth efficiency of CDMA are examined for various mobile operational environments. An analytical performance model is employed to assess the spectrum efficiency aspects of various CDMA transceiver architectures operating in both rural and urban cellular environments, as well as micro-cellular network topologies. From the results presented, it can be seen that a CDMA transceiver designed to exploit multipath activity within an urban cellular environment in order to obtain high bandwidth efficiency can also operate effectively in both rural and micro-cellular service areas, given identical spreading bandwidth allocations.<
