Statistical Model of Downlink Power Consumption in Cellular CDMA Networks
This work provides a theoretical framework for analyzing downlink power consumption in CDMA networks, which is useful for network planners and researchers, but the model is based on simplified assumptions and is incremental in nature.
The paper proposes a theoretical statistical model for downlink power consumption in cellular CDMA networks, deriving closed-form expressions for the first and second moments of power consumption under different cell selection and handoff schemes. Numerical results are provided for various propagation environments.
Present work proposes a theoretical statistical model of the downlink power consumption in cellular CDMA networks. The proposed model employs a simple but popular propagation model, which breaks down path losses into a distance dependent and a log-normal shadowing loss term. Based on the aforementioned path loss formalism, closed-form expressions for the first and the second moment of power consumption are obtained taking into account conditions placed by cell selection and handoff algorithms. Numerical results for various radio propagation environments and cell selection as well as handoff schemes are provided and discussed.
