Capacity and coverage management issues in the forward link of CDMA systems

Abstract

Abstruct- In 3G wireless systems the volume of data traftie is expected to be larger on the forward link than the reverse link This is one of the main reasons that contribute to the forward link being the limiting link for the capacity of 3C CDMA systems, Many different algorithms interact in complex ways to affect the achieved capacity and define the system’s operation and coverage. This work studies the impact of system algorithms and their parameters, like maximum base station power, power partitioning between overhead and traffic, and connection blocking algorithms. It examines their effect on forward link performance (e.g. capacity, coverage, call blocking and dropout probabilities). A dynamic system simulator is used to examine how these algorithms, and their parameters affect the sytem capacity/coverage tradeoff. KqtwordMDMA; forward link; capaciv; coverage; 36
