Resource Management in Ds-cdma Cellular Networks

Direct sequence code division multiple access (DS-CDMA) has been shown as the predominant access technology to provide high speed multimedia services in the next generation wireless cellular networks. The DS-CDMA cellular network significantly differentiates itself from the traditional narrowband TDMA/FDMA system, in which great capacity gain could potentially be achieved by taking advantage of its unique characteristics. This chapter addresses the resource management issues in DS-CDMA cellular networks. We first provide an overview of the DS-CDMA network and discuss the main challenges in the design of resource management schemes. We then examine several critical issues within the scope of resource management including congestion control, rate and power control, cell planning; and in particular with emphasis on call admission control. In addition, we also offer some insight and discussions on the performance aspects, strength and weakness of the existing proposals.
