Abstract

Power distribution for a multirate wideband CDMA system is investigated. The target power vector is expressed in terms of the spread bandwidth, user data rates, and user QoS specifications. The power distribution problem is solved via a decomposition of the traffic demand matrix, subject to a power constraint. Based on the power distribution law and the corresponding convergence conditions, simple yet efficient strategies for call admission and capacity evaluation are proposed.
