Abstract :
Due to the popularity of the World Wide Web stringent quality of service has to be exported to the wireless network devices. Additional synchronous CDMA channels for each wireless terminal are one possibility to guarantee the required quality of service. The aim of this paper is to show the significance of careful design of spreading sequences for the system performance. Three strategies for allocating spreading sequences are presented and compared. A lower bound on the average interference is given. It is shown which properties spreading sequences need so as to achieve the lower bound.
