Call Admission Control Scheme for Arbitrary Traffic Distribution in CDMA Cellular Systems
Date: September 2000
Creator: Akl, Robert G.; Hegde, Manju V.; Naraghi-Pour, Mort & Min, Paul S.
Description: This presentation discusses call admission control (CAC). The authors define a set of feasible call configurations that results in a CAC algorithm that captures the effect of having an arbitrary traffic distribution and whose complexity scales linearly with the number of cells.

CCAP: A Strategic Tool for Managing Capacity of CDMA Networks
Date: 1998
Creator: Akl, Robert G.
Description: This presentation discusses CCAP, a strategic tool for managing capacity of CDMA networks. CCAP is a graphical interactive tool for CDMA that calculates the coverage area, call capacity of a CDMA network, and subscriber network performance to optimize capacity.

Cell Placement in a CDMA Network
Date: September 1999
Creator: Akl, Robert G.; Hegde, Manju V.; Naraghi-Pour, Mort & Min, Paul S.
Description: This presentation discusses research on cell placement in a CDMA network. In order to enable iterative cell placement the authors use a computationally efficient iterative process to calculate the inter-cell and intra-cell interferences as a function of pilot-signal power and base station location.

Effects of Call Arrival Rate and Mobility on Network Throughput in Multi-Cell CDMA
Date: June 1999
Creator: Hegde, Manju V.; Akl, Robert G. & Min, Paul S.
Description: This presentation discusses call arrival rate and mobility. The effect of call arrival rate on the capacity of a code-division multiple-access (CDMA) cellular network is evaluated. First the inter-cell and intra-cell interferences of every cell on every other cell are calculated for a given network topology. Then the capacity region for the number of simultaneous calls in every cell is defined for specified system parameters. This region is used to evaluate the new call blocking and handoff call blocking probabilities.

Flexible Allocation of Capacity in Multi-Cell CDMA Networks
Date: July 1999
Creator: Akl, Robert G.; Hegde, Manju V.; Naraghi-Pour, Mort & Min, Paul S.
Description: This presentation discusses flexible allocation of capacity in multi-cell CDMA networks. The effect of reverse power levels on the capacity of a code-division multiple-access (CDMA) cellular network is evaluated. The inter-cell and intra-cell interferences of every cell on every other cell are first calculated for a given network topology. Based on this, the nominal power of users is increased by a factor the authors call the Power Compensation Factor (PCF) which enables small cells to overcome the excessive interference from adjacent large cells.
